Abstract
Recently, rainfall process over wireless radio links has
been designated as an unstable semi-Markovian queue with
chaotic service description during rain events. A formal
explanation for such queue service behaviour in natural queues
like rainfall phenomenon, may be related to the presence of
stratified cloud layers representing rain cells, during rain events.
In this paper, the concept of service aggregation of rainfall queues
obtained from ground measurements is examined in Durban
(29°52′S, 30°58′E) in South Africa and Butare (2°36′S, 29°44′E) in
Rwanda are further analysed. Our results suggest that ― two or
more parallel queue servers maybe present ― at different strata
in the troposphere during typical rain events at these sites.
