Abstract
Increase in air temperature, redistribution of annual precipitation and decline in snow cover were being observed on the territory of Novohrad-Volynskyi during the years 2000–2017. The average annual air temperature increase amounted 1,5 0С in comparison with the norm and the average monthly temperature increase amounted from 0,4 (in October) to 2,3 ºC (in July). Climate warming on the territory of the city is nonuniform – the periods of rapid temperature increase are being changed by fall in temperature. Deviation of average monthly temperatures from a climatic norm occurred overall years under investigation, except in March 2003, June 2006 and 2014, November 2011. The coldest in monitoring period, turned to be January 2006 (-28,8 d. C), the warmest – September 2015 (35,8 d. C). Despite the existing tendency toward precipitation increase on the territory of the city, total annual precipitation is 32,4 mm less than norm. The highest precipitation level is typical for the period from May to October and the lowest from November to April. In January, April, June, August, September, November the reduced amount of precipitations (as to the norm of 0,7–15 mm) has been observed, and during the rest 5 months (February, March, May, July, October) the amount of precipitations increased by 0,6–6,4 mm. The minimum precipitation amount was observed in November 2011 and in August 2015 (3,7 mm), the maximum – in July 2017 (199,2 mm). The solid precipitation decrease can be observed on the territory of the city. In a view of particular months the most snowy is February (the depth of snow cover is 10,1 sm), the least snowy is December with the depth of snow cover of 4,9 sm. Сoefficient of deviation essentiality confirmed a tendency to increase the percentage of months with conditions that are different from perennials: for temperatures from 27,8 to 44,4 % and for rainfall from 5,6 to 44,4 %, and conditionі close to extreme – 5,6 %.
