Variability of rainfall intensity between 1930 and 2010 in the central region of the State of Mexico. Perspectiva Geográfica [online]. 2025, vol.30, n.1, 16879.  Epub 28-Ene-2025.

The climate change has generated significant changes in local climate conditions. The objective of this investigation is to analyze the changes that have occurred in the intensity of the rain in the central region of the State of Mexico. To develop the investigation, an area with homogeneous precipitation was identified and information was obtained from the meteorological stations present on the site. 24-hour rain records from meteorological stations were categorized and with them a daily precipitation index was developed; simismically, parameters such as: daily evaporation, maximum daily temperature and minimum daily temperature were analyzed. Data was grouped by time (decades) and space (municipalities). With the temporal data, a trend analysis was carried out using the Mann-Kendall statistical test and the correlations between atmospheric variables were analyzed. An analysis was carried out with the spatial data using the Moran I index. The results show that light precipitation, moderate precipitation and the daily evaporation rate show a significant downward trend; accordingly, the average maximum daily temperature shows a significant trend towards alza; regarding spatial analysis, daily evaporation was the only variable that presented significant evidence of positive spatial autocorrelation. In conclusion, the average daily precipitation in the central region of the State of Mexico has been similar in recent decades; however, significant changes are occurring in its intensity.
