Why do we have rainfall?
Why do we have rainfall?
Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds. When the water droplets get too large and heavy, they fall as rain.
Can we predict rain?
Meteorologists use computer programs called weather models to make forecasts. Since we can’t collect data from the future, models have to use estimates and assumptions to predict future weather. The atmosphere is changing all the time, so those estimates are less reliable the further you get into the future.
Why does it rain after hot weather?
Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.
What part of the world rains the most?

Why does it never rain in the morning?
Why does it never seem to rain early in the morning from 6AM to 9AM? Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds. …
Why does it always rain at 5pm?
According to PAGASA, rain showers or thunderstorms usually occur in the afternoon or evening because of the heat accumulated from morning until the latter part of the day. When a cloud becomes massive, it can no longer sustain the moisture so it releases water through precipitation in the forms of rain, snow, or hail….
What time of day is it most likely to rain?
Both tend to be most frequent around 3-8 AM. This makes a lot of sense. We don’t get many thunderstorms around here and low clouds and drizzle sometimes occur when the region is flooded by marine air. Often the clouds burn off or lift by late morning….
Why does it rain a lot in West Ferris?
Answer: This idea helps students explain why more rain forms over West Ferris than East Ferris. Therefore, when students explain that water vapor condenses higher in the atmosphere, they are actually explaining that water vapor condenses high in the troposphere, which is relatively low in the atmosphere….
What causes the rain shadow effect?
Wind and moist air are drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the “rain shadow”.
What is the Olympic rain shadow?
The Olympic Rain Shadow is a small region northwest of the city of Seattle which experiences significantly dryer and brighter weather than surrounding locations. The rain shadow encompasses the towns of Sequim, Port Angeles, Port Townsend, Coupeville, and Victoria BC, as well as much of the San Juan Islands.
