Opis:
The subject of this paper is to analyse the climate change and its influence on the energy performance of building and indoor temperatures. The research was made on the example of the city of Kielce, Poland. It was was carried out basing on the Municipal Adaptive Plan for the city of Kielce and climate data from the Ministry of Investment and Development.The predicted, future parameters of the climate were estimated using the tool Weather Shift for Representative Concentration Pathways (RCP). The analysis took into consideration the RCP4.5 and RCP8.5 scenarios for years 2035 and 2065, representing different greenhouse gas concentration trajectories. Scenario RCP4.5represents possible, additional radiative forcing of 4.5 W/m2 in 2100, and RCP8.5 an additional 8.5 W/m2. The calculated parameters included average month values of temperature and relative humidity of outdoor air, wind velocity and solar radiation. The results confirmed the increase of outdoor temperature in the following year. The values of relative humidity do not change significantly for the winter months, while in the summer months decrease is visible. No major changes were spotted in the level of solar radiation or wind speed. Based on the calculated parameters dynamic building modelling was carried out using the TRNSYS software. The methodology and results of the calculations will be presented in the second part of the paper.
Przedmiotem artykułu jest analiza zmiany klimatu oraz jej wpływu na charakterystykę energetyczną budynku i temperaturę wewnętrzną. Badania przeprowadzono na przykładzie miasta Kielce. Ich podstawą był Miejski Plan Adaptacyjny dla miasta Kielce oraz dane klimatyczne z Ministerstwa Inwestycji i Rozwoju. Przewidywane, przyszłe parametry klimatu zostały oszacowane za pomocą narzędzia Weather Shift dla Representative Concentration Pathways (RCP). W analizie uwzględniono scenariusze RCP4.5 i RCP8.5 na lata 2035 i 2065, reprezentujące różne trajektorie wzrostu stężenia gazów cieplarnianych. Scenariusz RCP4.5 reprezentuje przewidywane, dodatkowe wymuszenie radiacyjne wynoszące 4,5 W/m2 w 2100 r., a RCP8.5 dodatkowe 8,5 W/m2. Wyznaczone parametry obejmowały średnie miesięczne wartości temperatury i wilgotności względnej powietrza zewnętrznego, prędkości wiatru i wielkości promieniowania słonecznego. Wyniki obliczeń potwierdziły wzrost temperatury zewnętrznej w kolejnych latach. Wartości wilgotności względnej powietrza nie zmieniają się znacząco dla miesięcy zimowych, natomiast w miesiącach letnich widoczny jest ich spadek. Nie zaobserwowano większych zmian w poziomie promieniowania słonecznego i prędkości wiatru. Na podstawie obliczonych parametrów przeprowadzono dynamiczne modelowanie budynku przy użyciu oprogramowania TRNSYS. Metodologia i wyniki obliczeń zostaną przedstawione w drugiej części artykułu.

Opis:
Urban regions are well known to be warmer than the outlying surrounding regions: this phenomenon is termed an Urban Heat Island (UHI). Depending upon its severity, an UHI can influence human health, the condition of urban vegetation, as well as air and water quality leading to a general decline in the living conditions of the affected urban environments and residents. Some studies have shown that prevailing weather conditions, like wind patterns, can influence UHI magnitudes. These studies suggest that wind speeds may be inversely related to UHI magnitude. However, long-term and high frequency weather and temperature measurements are exceedingly rare, so the exact nature of the relationship between wind speeds and directions as well as UHI magnitudes remain unknown. In order to address this problem, this study investigates how UHI magnitudes in five Australian cities affect wind speed and wind direction. The results of this study revealed that urban–non-urban temperature differences are most pronounced under calm weather conditions. The UHI intensity weakened as wind velocity increased: strong significant negative correlations were found between the mean UHI intensity and mean wind speed magnitudes. The results show that the greatest UHI intensities are recorded when wind is weak (less than $2 ms^{-1}$), while the lowest magnitudes are found when wind speeds exceed $6 ms^{-1}$. Further, the results show that the critical wind speed value, above which the strength of the UHI is considerably minimized, is around $4–5 ms^{-1}$. In addition, the study shows that wind direction in each city is a critical driver factor that determines the intensity of the UHI effect. When winds originate from dry environments, they favour high UHI intensities at all wind speeds, while the winds from the ocean side of coastal cities tend to cool urban regions, reducing UHI intensities or even promoting the urban cool island formation.

Opis:
Rapid changes in the major environmental variables like: temperature, wind and precipitation have occurred in the Antarctic region during the last 50 years. In this very sensitive region, even small changes can potentially lead to major environmental perturbations. Then the climate change poses a new challenge to the survival of Antarctic wildlife. As important bioindicators of changes in the ecosystem seabirds and their response to the climate perturbations have been recorded. Atmospheric warming and consequent changes in sea ice conditions have been hypothesized to differentially affect predator populations due to different predator life-history strategies and substantially altered krill recruitment dynamics.

Opis:
Wind constitutes one of the major environmental factors affecting the design and performance of built environment. Each country has its unique climatic wind conditions, and the way in which these are considered and implemented in the structural design, is important. An implementation or adoption of any new engineering design stipulations introduces a formidable challenge to the developers of the standards and the design profession. This has been experienced in some of the countries (e.g. the UK, Australia and the USA), where processes of modernising the outdated codification took place in the past. Although both Poland and South Africa are currently at the early implementation stage of the new wind loading design stipulations, there is a major difference between the circumstances of the two countries. Poland, as an EU member state, has a compulsory obligation to adopt the new uniform standarisation requirements, within a stipulated time-frame. The South African code developers, after a thorough investigation process which will be highlighted in the paper, decided voluntarily to adopt the Eurocode as the primary model document.

Opis:
Based on wind data from the Vilsandi meteorological station and a 5-month calibration measurement with a bottom-mounted Recording Doppler Current Profiler (RDCP), a semi-empirical hindcast of wave parameters near the quickly developing accumulative Kelba Spit is presented for the period 1966–2006. The significant wave heights with a gross mean value of 0.56 m exhibited some quasiperiodic cycles, with the last high stage in 1980–95 and a decreasing overall trend of −0.001 m per year. At the same time, both the frequency and intensity of high wave events showed rising trends, and the mean wave heights during winter (December to February) increased as well. As the study area has the longest fetches in westerly directions, the discussed tendencies in wave conditions are sensitive to regional changes in the wind climate and can be related to a decrease in the local average wind speed on the one hand, but an intensification of westerly winds, storm events and the wintertime NAO index on the other. The roughest wave storms on record were associated with prominent W-storms on 2 November 1969 and 9 January 2005; a few other extreme wind events (e.g. in 1967, 1999, 2001), however, did not yield equally prominent waves.

Opis:
W pracy analizowano warunki termiczne, opadowe oraz anemometryczne w Gdyni w latach 1923-1950, które można uznać za ekstremalne. Wyniki z lat 1923-1950 oceniono w odniesieniu do wielolecia referencyjnego 1971-2000 oraz całego okresu pomiarowego 1923-2014. Analizowano rozkłady empiryczne i teoretyczne wybranych elementów meteorologicznych. W przypadku temperatury powietrza wyznaczono wartości kwantyli 5, 10, 90 i 95% rozkładów empirycznych temperatury maksymalnej i minimalnej oraz częstość występowania dni upalnych, fal gorąca i dni bardzo mroźnych. Wyznaczono sumę opadów w ciągu roku podczas dni z opadem o ekstremalnej sumie dobowej, liczbę dni z opadem silnym i bardzo silnym, a także najdłuższe ciągi kolejnych dni z opadem oraz bez opadów. Wyznaczono wartości kwantyli 10 i 90% rozkładu miesięcznych sum opadów. Wyznaczono wartości maksymalnej prędkości wiatru o okresie powtarzalności 5, 10 i 50 lat z zastosowaniem rozkładów GEV (ang. Generalized Extreme Value). Najbardziej znaczące różnice ekstremalnych warunków termicznych pomiędzy rozpatrywanymi wieloleciami stwierdzono w przypadku rocznego rozkładu temperatury minimalnej, który ulega systematycznemu przesunięciu w kierunku wyższych wartości. Wykazano również wzrost najniższych wartości temperatury maksymalnej oraz spadek liczby dni bardzo mroźnych. Różnice ekstremalnych warunków opadowych w poszczególnych wieloleciach mogą świadczyć o zwiększeniu intensywności opadów w niektórych miesiącach półrocza ciepłego oraz wzroście zagrożenia niedoborem opadów w ciągu całego roku. Dodatnie różnice maksymalnej prędkości wiatru, o możliwości wystąpienia co najmniej raz na 50 lat, mogą wskazywać na wzrost ryzyka strat spowodowanych wystąpieniem silnego wiatru.
The aim of the research was to analyze the thermal, precipitation and anemometric conditions in Gdynia in the years 1923-1950, which can be considered as climate extreme. The results of the years 1923-1950 were evaluated for the reference period 1971-2000 and the whole measuring period 1923-2014. The empirical and theoretical frequency distributions of selected meteorological elements were analyzed. Statistical characteristics of the extreme thermal conditions (the values of 5, 10, 90 and 95% quantile of the empirical distributions) as well as the frequency of sweltering days, hot waves and very ice days were determined. Heavy and very heavy precipitation days, the amount of precipitation during days with extreme daily precipitation amount and the longest periods of consecutive days with precipitation and with no precipitation were determined. The maximum wind speed values of 5, 10 and 50-year return period was estimated with the use of Generalized Extreme Values analysis (GEV). The most significant differences in the extreme thermal conditions between the considered periods were found in the annual minimum temperature frequency distribution, which has been shifted towards higher values. It also showed an increase in the lowest values of the maximum temperaturę and a decrease in the number of very cold days. Results related to extreme precipitation conditions may indicate the intensity of precipitation events in some months of the warm season and an increase the risk of meteorological drought over the whole year. The expected return level of the extreme wind speed for 50 year return period, determined in relation to the periods considered, indicates an increase in the risk of losses caused by strong wind.

Opis:
This study provides an assessment of the current and future changes (in terms of both direction and value) in air temperature, precipitation, snow, wind and their extremes over the territory of Belarus using information from 42 meteorological stations and 92 regional circulation model (RCM) simulations with the highest available horizontal resolution (EUR-11). Three representative concentration pathway scenarios, namely, RCP2.6, RCP4.5 and RCP8.5, are considered. Results demonstrate that in recent decades, temperature has increased over the territory of Belarus by 1.3°C, with the largest increase occurring during the cold season (2.1-2.3°C). Ensemble scenarios project further increases in air temperature in the current century by +0.5-1.5°C, +2.8°C, and +5.2°C under the RCP2.6, RCP4.5 and RCP8.5 scenarios, with the largest increase during the cold season under the RCP8.5 scenario. The annual means were observed to increase (insignificantly) by 5-7% and the summer precipitation extremes exhibited a 20-25% growth in recent decades. Moreover, dry conditions have intensified in Belarus, particularly during the growing season. Further increases in precipitation of 10-15% across Belarus are projected to occur in all seasons under the RCP4.5 and RCP8.5 scenarios. Simulation models predict greater increases in single day rainfall events compared to their multiday precipitation counterparts. The greatest increases in maximal dry period length (by 1-2) are expected to occur in summer and autumn. The models project the general decrease in snowfall across Belarus to continue into the current century, with a reduction in snow precipitation days of 10-30 days. Despite the reduced wind strength (by 0.9-1.0 m·s -1 ) since the 1970s over the territory of Belarus, the ensemble model reveals slight nonsignificant changes in seasonal and annual wind strengths until the end of the century. Significant changes of 1-3 days under varying directions of the wind regime were observed for days with a strong breeze and storms.

Opis:
The purpose of this work was to analyze the influence of climatic variability of wind waves and swell parameters in the coastal zone on the sediment transport and to assess the contribution of the swell to the formation of alongshore fluxes. The object of research is the Anapa bay-bar (the Black Sea). Mathematical modeling has shown that in the Anapa bay-bar area the average annual wind waves and swell powers have significant interannual variability. For the period from 1979 to 2017, in the southern part of the bay-bar, there was a statistically significant decrease in the share of swell in the alongshore transport, directed from NW to SE, in the central part – an increase in the contribution of swell to the total sediment flow from SE to NW, in the northern part – probable increase in flows to NW and decrease – to SE. Such a dynamic is consistent, in general, with experimental observations of the processes of erosion and accumulation of beach-forming material along the Anapa bay-bar coastline. A separate description of the bottom sediment fluxes under the influence of wind waves and swell made it possible to explain the fluctuations of the coastline over a climatic period.

Opis:
The response of semi-realistic wind speed increase scenarios to the mean sea level and current regime of semi-enclosed sub-basins in the Baltic Sea is studied with a 2D hydrodynamic model. According to the model output of spatial mean sea levels, an increase in the westerly wind component by 2 m s−1 leads, for example, to a mean sea level rise of up to 3 cm in windward locations in the study area. The sea level change patterns depend on the wind scenario and coastline configuration. The increases in wind speed considered here also lead to enhanced water exchange through the straits, strengthening of the basin-scale circulation, enhancement of up- and downwelling, and increased bottom stresses near coasts.

Opis:
This study tackles the question: Do very high-resolution convective-permitting regional climate model (RCM) simulations add value compared to coarser RCM runs for certain extreme weather conditions, namely strong wind and storm situations? Ten strong storm cases of the last two decades were selected and dynamically downscaled with the RCM COSMO-CLM (24 and 2.8 km grid point distance). These cyclones crossed the high-resolution model domain, which encompasses the German Bight, Northern Germany, and parts of the Baltic Sea. One storm case study (storm Christian of October 2013) is discussed in more detail in order to analyze the smallscale storm features and the associated potential added value of the high-resolution simulation. The results indicate an added value for atmospheric dynamical processes such as convective precipitation or post-frontal cloud cover. The multiple storm analysis revealed added value for the high-resolution regional climate simulation for 10 m wind speed, mean sea level pressure, and total cloud cover for most storms which were examined, but the improvements are small. Wind direction and precipitation were already well simulated by the coarser RCM and the higher resolution could often not add any value for these variables. The analysis showed that the added value is more distinct for the synoptic comparisons than for the multiple storm study analyzed with statistical measures like the Brier Skill Score.
