CARLON ALLENDE, Teodoro  and  MENDOZA, Manuel E. Hydrometeorological analysis of Cuitzeo Lake watershed. Invest. Geog [online]. 2007, n.63, pp.56-76. ISSN 2448-7279.

Time series analysis of hydrometeorogical data is an excellent tool for analyzing climate evolution in the past and present. The subject in this research was to analyze temperature, precipitation and runoff time series from hydro-meteorological stations located in (and close by) the subwatersheds of Cointzio, San Marcos and Querendaro, which are located in Cutzeo Lake watershed, Michoacán. Firstly a climatic description based on climograms is presented; as it was expected, the highest temperatures were observed in April, May and June. The trend analysis of precipitation, temperature and runoff was carried out using a nonparametric Mann-Kendall test. Trend analysis indicated mean temperature from Morelia station increase at significant level, in both monthly and annual values; while, records from Cuitzeo and Huingo stations indicated a decrease trend at significant level. Annual precipitation from Huingo and Jesus del Monte indicated and increase at significant level.

Keywords : Trend analysis; time series; hydrometeorology; Cuitzeo lake water shed; Mexico.
