Opis:
A major source of energy on Earth is solar irradiation. This paper uses the Kolmogorov-Zurbenko filter to smooth and examine sunspot numbers and proves that solar irradiation levels near Earth are strictly proportional to sunspot numbers. This paper also examines the transport of that energy through the atmosphere to Earth’s surface. Long term air temperatures on the surface of Earth perfectly follow the cosine square law along latitudes. Time components of long term temperatures have oscillations which follow oscillations in sunspot numbers, but due to the regular delays in energy transmission they are delayed 4-7 years. Cloud formations and vapor accumulations also contribute to those delays, which have a well-organized time-space structure. The main purpose of this paper is the numerical identification of human influence over changes in solar activities, which may allow researchers to identify the effects of various sources of those influences. This evaluation can only be achieved by separating the scales in order to avoid any false influence from other scales. The clear separation of scales can only be achieved using the Kolmogorov-Zurbenko filter.

Opis:
This study aims at studying the characteristics of some meteorological variables in Sokoto and its vicinity using probability distribution models. The thirty one (31) years data (i.e 1980-2010) were collected at Nigerian Meteorological Agency (Nimet) Oshodi and the data were subjected to various probability distribution analyses in order to resolute the best fit probability functions for each meteorological variables. The variables measured consist of Relative humidity, Rainfall, Temperature, Sunshine hours, Solar radiation, wind speed and Evaporation pitche. Whereas the probability distribution models adopt were Normal, Gumbel, Pearson type III and Log-Pearson type III distribution functions. Numerical equation were recognized and used to forecast the variables. Goodness of fit tests such as chi-square, correlation coefficient and coefficient of determination were carried out to obtain the reliability of the forecasted values. The model that satisfies the statistical tests conditions mostly was selected as the best fit model. The study revealed that Rainfall, wind speed, evaporation pitche are best fitted by Log-pearson type III probability distribution model, whereas the Relative humidity, solar radiation, sunshine hours and temperature the best model is Gumbel probability distribution.
