Glendora Random Weather Fact
Orographic Enhancement
(also called Orographic Precipitation) -- Precipitation which is caused by hills or mountain ranges deflecting the moisture-laden air masses upward, causing them to cool and precipitate their moisture. In Glendora, this occurs when warmer, subtropical storms travel northward over Glendora. As the airmass approaches the foothills, the airmass is pushed upward by the rising elevation of the foothills. As the airmass increases in altitude, the clouds are cooled and heavy rains result. Strictly speaking, orographic enhancement refers to the precipitation directly attributed to the mountain relief, and not the total amount of precipitation received in a given area.
