dc.description.abstractAssessment of Climate Aridity Trends in the Southern Region of Ukraine was conducted using data meteostations for the period 1991-2020. The analysis of climate aridization trends over the past 30 years in the study region has revealed a notable intensification of this process, especially in recent years. The hottest summer months occurred in 1992, 1999, 2001-2003, 2007, 2010, 2012, and 2017-2019. These periods were marked by anomaly high temperatures, dry winds, extended non-rainfall periods, and low air humidity, often reaching as low as 30%. Over the past 30 years, from March to October, the Southern Region experienced an average of 203±6 non-rainfall days, with a trend indicating an increase by an average of 0.4±0.1 days per 10 years. Conversely, the number of days with relative humidity up to 30% on the March–October time scale averaged 41±16 days, with a tendency to increase by 1.2±0.7 days per 10 years. The highest occurrence of days with relative humidity up to 30%, on average in the region, is typically observed in July and August (7 and 10 days per month, respectively). To assess climate aridity and calculate drought severity for vegetation were used a satellite-derived Vegetation Health Index (VHI). Drought indices derived from the summed VHI values in August for the years 2007, 2018, and 2020 in the Southern Region of Ukraine are presented.en_US
