Long-term trends of the annual and daily depths of the precipitation layer in Kyiv, Odesa, and Lviv

Ілляш, О.Е.

A comprehensive analysis of long-term series of daily precipitations in Kyiv, Lviv, and Odesa in 1945-2021 is performed. Similar trends in the change of base rainfall parameters are obtained for all cities. The annual depth of precipitation layer systematically increase, with average speed of 1.61 mm•yr-1 for Lviv, 1.25 mm•yr-1 for Odesa and 0.22 mm•yr-1 for Kyiv. The annual number of wet weather days has a still tendency for decreasing, with the highest rate for Kyiv (0.42 yr-1), and lowest rate for Odesa (0.08 yr-1). The average daily depth of precipitations for 1945-2021 increases at almost the same rate, from 0.014 to 0.016 mm•day-1 •yr-1. Dependences of the maximum daily rainfall depths on the return period 0.1-10 yr are obtained using the Weibull model.
