dc.description.abstract | This study investigated recent trends in the mean surface minimum and maximum air temperatures over eastern
Africa by use of both graphical and statistical techniques. Daily records for 71 stations for the period \939-92
were used.
Attempts were also made to associate the temperature characteristics with the anomalies in the major systems
that control the climate of the region including the EI Nino-Southern Oscillation (EN SO), the quasi-biennial
oscillation, and the prevailing convective processes represented by the outgoing long wave radiation.
The northern part of the study region generally indicated nighttime warming and daytime cooling in recent
years. The trend patterns were, however, reversed at coastal and lake areas. The Mozambique channel region
showed cooling during both nighttime and daytime. There were thus large geographical and temporal variations
in the observed trends, with some neighboring locations at times indicating opposite trends.
A significant feature in the temperature variability patterns was the recurrence of extreme values. Such
recurrences were significantly correlated with the patterns of convective activities, especially ENSO, cloudiness,
and above/below normal rainfall. Although some of the variations in the trend patterns could be attributed to
urbanization and land use patterns, such effects were not delineated in the current study. | en |
