Global climate projections indicate a steady increasing trend in surface temperatures around the globe. This is more pronounced in the recent decades.
Attempts have been made to explain this trend with studies indicating a significant increase started at around the industrialisation time in the mid ninetieth century, therefore, attributing the increase to increased generation of fossil fuels at the time resulting in increasing carbon dioxide in the atmosphere. The observed changes in the temperature regimes over time lend credence to this assertion.
To understand the trend over central Europe in the most recent times, this study will examine the spatial temporal variations and diurnal range of temperature using two data sets ERA5 and E-OBS. Variability at monthly, seasonal, annual, and decadal timescales are covered, focusing on the period 1979 to 2020.
It utilises various statistical methods, including least square fitting and standard statistics. The results indicate general warming trend over the region and the study concludes that there is observed gradual warming from decade to decade.
