Long-term variations of annual and growing season rainfalls in Nigeria
Autor: G. N. Sumner, O. J. Olaniran
Publikováno v: Theoretical and Applied Climatology. 41:41-53
Evidence for changes in the annual and growing season rainfall series for the period 1919 to 1985 in Nigeria are examined on a regional basis, using power-spectral and lowpass filter techniques, and the Mann-Kendall rank statistic. Four regions, the

Characteristics of Storms over Urban Areas in East Africa
Autor: G N Sumner
Publikováno v: Water Science and Technology. 16:47-62
Storm morphologies and associated intensity profiles are examined using data taken from dense pluviograph networks in East Africa. Different morphologies of storms are illustrated with use of examples for Dar es Salaam, Tanzania and Kampala, Uganda.

The nature and development of rainstorms in Coastal East Africa
Autor: G. N. Sumner
Publikováno v: Journal of Climatology. 1:131-152
Using data for a 29-month period from an intense network of extended scale autographic raingauges at Dar es Salaam, various different storm types are identified, which are thought to be representative of the East African coast as a whole. The primary

A study of climatic variability in Nigeria based on the onset, retreat, and length of the rainy season
Autor: O. J. Olaniran, G. N. Sumner
Publikováno v: International Journal of Climatology. 9:253-269
The long-term variability of rainfall conditions in Nigeria in terms of the onset, retreat, and length of the rainy season has been analysed, using pentad data for the period 1919–1985. Data were grouped into four areas, arranged in a south-north t

Daily Rainfall Variability in Coastal Tanzania
Autor: G. N. Sumner
Publikováno v: Geografiska Annaler: Series A, Physical Geography. 65:53-66
The spatial correlation analysis of daily rainfall data for a 29 month period in the northern coastal area of Tanzania has revealed a definite trend of higher rainfall correlations parallel to the coastline than is apparent normal to it. The general
