Transformation of Level of Humidification in the Eastern Part of Cuba

Abstract

The work is devoted to analysing the transformation of humidification in a changing climate in the eastern part of Cuba, the case of Holguin (east of the island). The importance of the study is related to the need to study precipitation trends in certain regions. Based on the analysis of the long-term dynamics of annual precipitation values, relative humidity, and the number of days with precipitation, trends in the degree of moisture in the east of the island was established. The practical significance of the work lies in identifying and developing long-term weather forecasts and planning the economic and recreational development of the territory. The 1970–2020 period was considered. Changes in the amount of precipitation and days with precipitation were analysed. The moisture coefficient for the territory was calculated. The wettest and driest periods were identified, with the wettest being from 1981 to 1985 and the driest being from 1991 to 1995. The average rainfall for the wettest period was 1365 mm, while the average rainfall for the driest period was 335 mm. There was an increase in the number of days with precipitation from 39 days (1970) to 150 (2007). The maximum values of days with precipitation occurred in the period from 2006 to 2010. The calculated balance of humidification of the territory revealed heterogeneity of conditions of humidification of the territory. The maximum moisture deficit falls in the period from February to April, and the minimum – in June. The annual moisture balance was -653 mm. The territory is experiencing a lack of moisture.
