CLIMATIC PATTERN ANALYSIS OF RAINFALL AND DRY SPELLS DURING THE AGRICULTURAL SEASON IN MALAWI by Medrina Linda Mloza Banda, Wim Cornelis, Henry R. Mloza Banda

“…Utilizing observed daily station rainfall datasets from the rainy season (November to April) spanning the years 1961 to 2007, a set of indices including percentile, absolute, threshold, and duration measures, was derived for locations at low (Balaka), medium (Bunda, Chitedze, KIA), and high (Dedza) altitudes in Malawi. For each site, a separate analysis was conducted in which the indices were subjected to principal component analysis, followed by composite analysis and K-means clustering of the extracted principal components. …”
