| Abstract | En este trabajo se analiza la variabilidad espacio-temporal de las sequías en Cali, Colombia, y sus principales relaciones con El Niño-Oscilación del Sur (ENOS). El índice de precipitación estandarizada (SPI) se utilizó para detectar eventos de sequía a partir de los datos de precipitaciones mensuales de 24 estaciones bien distribuidas en Cali durante 1971-2011. El SPI proporcionó la intensidad, magnitud, frecuencia y umbrales mínimos de la sequía, principalmente en escala anual (SPI-12). El 80% de las estaciones reportaron cuatro eventos con condiciones secas en Cali: 1976-1977, 1983-1984, 1990-1992 y 2009-2010. La influencia de ENOS fue evaluada usando los análisis de correlación y la transformada de wavelet. Se observaron correlaciones negativas significativas (no significativas) entre el SPI-12 en el norte (sur) de Cali, y el índice multivariado de ENOS (MEI), y los índices Niño 3.4 y Niño 4 de la temperatura de la superficie del mar (TSM). El análisis de coherencia de wavelet mostró coherencias significativas entre ENOS y SPI-12: a escala interanual (4-6 años), la diferencia de fase de 135º genera un retraso de 6-9 meses entre el pico mínimo del SPI-12 y el pico máximo de los índices. Para la escala cuasi-bienal (2-3 años), la diferencia de fase de 180º sugiere que las condiciones máximas de humedad (secas) coinciden con la etapa de madurez del evento de La Niña (El Niño); y para la escala decadal (8-16 años), las disminuciones (aumentos) en la precipitación preceden a la etapa de madurez de El Niño (La Niña) en aproximadamente 10-18 meses. Estos resultados son relevantes para el pronóstico estacional, ya que los cambios en la TSM del Pacífico ecuatorial pueden ocurrir 6-18 meses antes de las condiciones secas de Cali. ABSTRACT: This paper analyzed the spatio-temporal variability of droughts in Cali, Colombia and their primary relations to the El Niño Southern Oscillation (ENSO). The Standardized Precipitation Index (SPI) was used to detect drought events from monthly rainfall data of 24 stations well spread over Cali during 1971-2011. The SPI provided the drought intensity, magnitude, frequency, and the minimum rainfall thresholds, mainly on an annual scale (SPI-12). Eighty percent of the stations reported four events with dry conditions in Cali:1976-1977, 1983-1984, 1990-1992 and 2009-2010. The ENSO influence was evaluated using the correlation and wavelet transform analyses. Significant (non-significant) negative correlations between SPI-12 in the northern (southern) part of Cali, the multivariate ENSO Index (MEI), and Sea Surface Temperature (SST) Niño 3.4 and Niño 4 indices were observed. The wavelet coherence analysis showed significant coherencies between ENSO and SPI-12: at interannual scale (4-6 years), the phase difference of 135º generates a lag of 6-9 months between the minimum peak of the SPI-12 and the maximum peak of the indices. On the quasi-biennial scale (2-3 years), the phase difference of 180º suggests that the maximum wet (dry) conditions coincide with the mature stage of the La Niña (El Niño) event; and on the decadal scale (8-16 years), the decreases (increases) in rainfall precede the El Niño (La Niña) mature stage by approximately 10-18 months. These results are relevant for seasonal forecasting, since changes in SST in the equatorial Pacific may take place 6-18 months ahead of the dry conditions in Cali. | |||
