The purpose of this research was to determine the amount, frequency and trends of precipitation deficits in the cultivation of winter wheat in central and eastern Poland, over a period of fifty years (from 1971 to 2020). This study used the values of average monthly air temperatures, as well as monthly total precipitation, decadal precipitation needs of winter wheat within central and eastern Poland. Based on the performed research, both spatial and temporal differences were observed in the scope of the amount and frequency of precipitation deficits in the cultivation of winter wheat. The lowest risk of precipitation deficits was found in May (from 15% to 32%), which is a critical month in the cultivation of this plant in Poland, while the highest risk of precipitation deficits was observed in June (from 22% to 56%), which is an unfavourable phenomenon, because winter wheat is in the so-called grain filling phase since mid-June. It was also found that there is a statistically significant upward trend of the winter wheat's precipitation needs in April, June, and July. An increase in the inflow of warm and dry air masses from the southern sectors was one of the factors impacting the amount and frequency of precipitation deficits in the cultivation of wheat. The problem of climate warming that has been increasing in recent years, and - as a consequence - an increase in precipitation deficit during the growing season of plants, demonstrate the need for further research in this scope.

The aim of the study was to assess the spatiotemporal variation of atmospheric (meteorological) drought in agricultural areas of east-central Poland, represented by the Lublin Voivodeship (Lublin region) in 1971-2015. Average monthly air temperatures and monthly precipitation totals recorded over the 45-year period at 25 weather stations were used in the study. The assessment of spatiotemporal variation in atmospheric drought in the study area was based on calculations of the aridity index. The analysis showed an increase in the severity of atmospheric drought in the Lublin region, with intensification of this phenomenon in the last two decades, especially in the warmer half of the year (April, June-August). The main cause of drought in the Lublin region was identified as a statistically significant increase in air temperature (on average, from 0.4 °C to 0.7 °C/10 years in April, July and August, and from 0.2 °C to 0.5 °C/10 years in June) together with the absence of changes in precipitation in the warmer half of the year. This may be linked to some increase in the frequency of high-pressure circulation types, both non-directional and advection from the south. Due to the worsening problem of drought in Poland in recent years, especially in agriculture, there is a need for further research on this subject and for solutions aimed at optimizing agricultural use of the productive environment.

Finely-laminated lake sediments, dated at 8.5-6.7 cal kyr B.P., were examined in terms of lithology, geochemistry, microfossils (diatom, pollen) and magnetic susceptibility. Based on the inferred geographical derivation of pollen, the environmental affiliation of diatom taxa and geochemistry of lake sediments, wind trajectories were distinguished, related to two main atmospheric circulation phases. During the earlier phase (8.50-7.83 cal kyr B.P.) there were northwestern wind trajectories followed by southern ones and during the later phase (7.83-6.70 cal kyr B.P.), the northern winds were followed by northwestern and southern ones. Northwestern and northern winds brought winter rainfall and caused water turbulence in the lake, and the southern winds were associated with regional aridification. This scenario of atmospheric circulation in northeastern Africa extends significantly our understanding of key modes of climatic variability and wind trajectories in the Early to Middle Holocene (Greenlandian to Northgrippian) transition.
