What are the effects of regions with high precipitation?
Some presently dry regions may be glad to see increased rainfall, just as drier conditions may benefit some currently very wet places. However, heavy rainfall that causes flooding as well as extended or more frequent droughts are likely to be disruptive to ecosystems and agriculture in the afflicted regions.
How do mountains and hills affect climate?
Fourthly, mountains themselves play a major role in influencing regional and glo- bal climates. They act as barriers for wind flow, which induces enhanced precipita- tion on the windward side, and reduced precipitation and warmer temperatures on the leeward side.
How does terrain affect climate?
The topography of an area can influence the weather and climate. Topography is the relief of an area. If an area is close to a body of water it tends to make milder climates. Mountainous areas tend to have more extreme weather because it acts as a barrier to air movements and moisture.
Why hilly areas get more rain?
Because of the mechanism explained above, atmospheric water tends to precipitate when an air mass is lifted and cooled when it reaches a mountain range. Windward slopes typically received significantly more rains than the leeward slopes.
What are the effects of increased precipitation?
The potential impacts of heavy precipitation include crop damage, soil erosion, and an increase in flood risk due to heavy rains (see the River Flooding indicator)—which in turn can lead to injuries, drownings, and other flooding-related effects on health.
Do hilly areas get more rain?
Due to the greater width of the mountains, the rain bearing winds have to necessarily travel a longer distance and have more time for the drops to coalesce and precipitate as rainfall, resulting in higher rainfall. …
Does it rain more in hilly areas?
They receive more rainfall than low lying areas because the temperature on top of mountains is lower than the temperature at sea level. Winds carry moist air over the land. As the air rises, it cools, and because cool air can carry less moisture than warm air, there is usually precipitation (rain).
