Climatic characterization of the southern circuit of Cumanayagua, Cienfuegos, Cuba

Abstract

Knowledge of climatic characteristics on a local scale is vital for the development of diverse economic and social activities, especially in sectors such as agriculture, which in Cuba are fundamental for the economy due to their dependence on climatic factors. The aim of this study was to characterize the meteorological variables in the southern circuit of the municipality of Cumanayagua, in the province of Cienfuegos. For this purpose, we used the preliminary results of the Agroclimatic Atlas of Cienfuegos, the digital database of all meteorological variables from 62 meteorological stations of the Meteorological Institute Network, and the 4x4 km grid used in previous climatic and agrometeorological research, considering the climatic reference period 1991-2020. It was observed that the mean annual temperature fluctuates between 19-20°C in the mountainous regions and between 25-26°C in the coastal zone. Temperature extremes show minimum values that varied between 22-23°C on the coast and may decrease below 18°C in the highland areas. During July, maximum temperatures exceed 27°C on the coast and reach 21-22°C at higher altitudes. Average annual cumulative rainfall totals 1,608.1 mm. This analysis will provide users, decision makers and investors with a better understanding of climatic conditions, facilitating their cognitive preparation for economic development in various areas.
