Term
Orographic rainfall
Precipitation associated with air being lifted over high ground. Rising air expands and cools; if it becomes saturated, cloud can form and precipitation may follow. The lee side may receive less rain, depending on the wider weather pattern.
What to look for
A föhn cloud wall above Cilaos, Réunion. Moist air rises on the windward side; descending air on the lee side warms as it is compressed.
