CLIMATE CHANGE IN SOFIA
Abstract
Whether it is climate fluctuations or lasting one-way changes, it is clear that the climate today is not the same as it was a few decades ago. The question is no longer whether the change of climate exists, but in what way and to what extent it affects nature, man and his activity, how to mitigate it, and how to adapt to it. For this purpose, however, it is necessary to accurately determine the magnitude and direction of change of individual climatic elements and phenomena, given their diverse manifestations at the local level. This is especially true in urban areas, where a large part of the population is concentrated. Here climate change is becoming even more tangible as a result of the highly transformed underlying surface and air pollution. This is why many research on climate change is focusing on big cities. The aim of the present study is to establish the long-term trends of change of basic climatic parameters in the largest city in Bulgaria - the capital Sofia. For this purpose, based on the historical climatic period 1967 - 2019, the algorithms of changing the following climatic elements are determined: air temperature, precipitation, wind speed, number of days with rainfall, with snowfall, with storms, with hail and with fog. Based on the determined algorithms, the values of these climatic elements are projected to future time horizons, in 10 years, until 2100. The results are of interest not only from a purely scientific point of view, but also for all economic sectors experiencing the impact of changing the climate.
