Abstract:
This paper focuses on the analysis of precipita-<br/>
tion patterns, using a Local Area Weather Radar to collect<br/>
information about the precipitation distribution in an<br/>
Andean region of southern Ecuador (cities of Loja, Zamora<br/>
and Catamayo). 54 representative events were selected to<br/>
develop daily precipitation maps and to obtain their rele-<br/>
vant characteristics, which were related to the topography<br/>
and the season. The results showed that a strong correlation<br/>
between the areas covered by precipitation (RA coef?cient)<br/>
and the season exists. In general, humid air masses come<br/>
from the east (Amazon Basin), but during the main rainy<br/>
season (December to April), humidity also frequently<br/>
enters the study region from the west (Paci?c Ocean). The<br/>
rainy season is characterized by convective precipitation,<br/>
associated with higher evaporation rates during austral<br/>
summer. The relatively dry season is formed between May<br/>
and November, but considerable precipitation amounts are<br/>
registered, too, due to advective moisture transport from<br/>
the Amazon Basin, a result of the predominant tropical<br/>
easterlies carrying the humidity up the eastern escarpment<br/>
of the Andes, generally following the natural course of the<br/>
drainage systems.
