The formation and development of cumulus clouds are closely monitored by weather forecasters, as they can provide timely warnings for potential severe weather events. Stratus clouds, with their extensive coverage and low altitude, can block sunlight, leading to overcast and gloomy conditions. They often accompany light rain or drizzle and can persist for extended periods, affecting visibility and contributing to a cool and damp atmosphere.

Seasonal Trends in Precipitation

The southwest monsoon, which brings moisture-laden air from the Indian Ocean, plays a major role in fueling the wet season. The presence of the Sierra Madre mountain range, located to the east of Calapan, also contributes to the high rainfall. Orographic uplift, as moist air rises over the mountains, leads to condensation and precipitation.
