Opis:
This article is an analysis of how the World Meteorological Organization (WMO) constituent bodies governance reform (WMO Reform) can affect the activities of the Polish National Hydrological and Meteorological Service. The analysis employs the SWOT (Strengths, Weaknesses, Opportunities, Threats) model. The World Meteorological Congress is the highest authority of the World Meteorological Organization, whose findings guide the operations of the WMO and the National Meteorological and Hydrological Services (NMHSs) globally. During the 18th Congress, in June 2019, discussions covered the routine operations of the WMO and its Secretariat, the status and development prospects of all the Organization's research and technical programs, and the Organization's budget for the 18th financial period beginning in 2020. The key actions of the Congress, however, were the election of the WMO senior officers and final approval (after thorough discussion) of the WMO Reform of its governance structure. The purpose of the Reform is to ensure better preparation of the organization for the challenges of the present and future, such as climate change and its impact, the growing number and intensity of extreme weather events, environmental degradation, and increasing urbanization. The tasks of the National Hydrological and Meteorological Service in Poland are performed by the Institute of Meteorology and Water Management - National Research Institute (IMGW-PIB), in accordance with the provisions of the Water Law.

Opis:
The Global Navigation Satellite System (GNSS) can be used to determine accurate and high-frequency atmospheric parameters, such as Zenith Total Delay (ZTD) or Precipitable Water Vapour (PW), in all-weather conditions. These parameters are often assimilated into Numerical Weather Prediction (NWP) models and used for nowcasting services and climate studies. The effective usage of the ZTDs obtained from a ground-based GNSS receiver’s network in a NWP could fill the gap of insufficient atmospheric water vapour state information. The supply of such information with a latency acceptable for NWP assimilation schemes requires special measures in the GNSS data processing, quality control and distribution. This study is a detailed description of the joint effort of three institutions – Wrocław University of Environmental and Life Sciences, Wrocław University, and the Institute of Meteorology and Water Management – to provide accurate and timely GNSS-based meteorological information. This paper presents accuracy analyses of near real-time GNSS ZTD validated against reference ZTD data: the International GNSS Service (IGS) from a precise GNSS solution, Weather Research and Forecasting (WRF) model, and radiosonde profiles. Data quality statistics were performed for five GNSS stations in Poland over a time span of almost a year (2015). The comparison of near real-time ZTD and IGS shows a mean ZTD station bias of less than 3 mm with a related standard deviation of less than 10 mm. The bias between near real-time ZTD and WRF ZTD is in the range of 5-11 mm and the overall standard deviation is slightly higher than 10 mm. Finally, the comparison of the investigated ZTD against radiosonde showed an average bias at a level of 10 mm, whereas the standard deviation does not exceed 14 mm. Considering the data quality, we assess that the NRT ZTD can be assimilated into NWP models.

Opis:
This paper presents an analysis of the derecho phenomenon that occurred over Poland on August 11, 2017. The storm caused 6 fatalities, 39 injuries (Mańczak et al. 2022), and some of the greatest damage in the history of Polish forestry. Our study is based on radar meteorology and measurements from the Polish POLRAD radar network, and intended for advanced meteorologists with good knowledge of radar measurements. The research used both standard and specialized radar products as well as classic and Doppler scan data. The Doppler velocity products were especially useful for showing the characteristics of the storm. The analysis was mainly based on data from two radars: Poznań and Gdańsk, but the composite maps, consisting of data from more than one radar, were also analyzed. The derecho complex developed from unorganized thunderstorm cells over SW Poland and moved toward the NE. The various stages of the evolution of the system are presented and analyzed, accounting for the formation of a SC, the development of a rear inflow jet (RIJ), the split of the entire system, and the appearance of the bow echo signature. Significant factors affecting the scale of the wind damage were: (1) the extensive mesocyclone which evolved to the mesoscale convective vortex (MCV), and (2) a strong rear flank downdraft interacting with the rear inflow jet (RIJ).
