| dc.description.abstract | The objective of this study was to determine
relationships between satellite derived outgoing long wave
radiation (OLR) and several meteorological parameters using
correlation and regression analyses. The meteorological
parameters included rainfall, rain-days, moisture budget,
cloud cover, incoming radiation and surface temperature.
Principal component analysis (PCA) was further used to study
the spatial and temporal characteristics of OLR and rainfall.
The first step in the study involved the estimation of
the few missing records. The quality of the estimated
records was examined before they were included in the study.
Both point and areally averaged records were used in the
study for the four standard seasons namely March-May, June-
August, September-November and December- February.
The results from correlation analysis revealed
significant correlation between OLR and the various
meteorological parameters. The correlations between point
records were generally weak compared to those obtained for
areal records. | en |
