What is a monsoon weather?
A monsoon is a seasonal shift in the prevailing wind direction, that usually brings with it a different kind of weather. It almost always refers to the Asian monsoon, a large region extending from India to Southeast Asia where monsoon conditions prevail.
Figure A compares seasonal shifts in the monsoon circulation. Most of the time during the summer, the land is warmer than the ocean. This causes air to rise over the land and air to blow in from the ocean to fill the void left by the air that rose. As you know, rising air leads to cloud formation and precipitation.
- The land is warmer and the air over land is lower in density; wind flows from sea to land. With extensive seasonal change of wind direction, it is called a "monsoon". The southwest monsoon can bring the wet oceanic air into inland Asia and generate continuous precipitation.
- After the first initial downpour, which can last for days, the monsoon falls into a steady pattern of raining for at least a couple of hours most days. It can be sunny one minute and pouring the next. The rain is very unpredictable.
- The only difference between a hurricane, a cyclone, and a typhoon is the location where the storm occurs. Hurricanes, cyclones, and typhoons are all the same weather phenomenon; we just use different names for these storms in different places. In the Atlantic and Northeast Pacific, the term “hurricane” is used.
The tropical monsoon climate experiences abundant rainfall like that of the tropical rain forest climate, but it is concentrated in the high-sun season. Being located near the equator, the tropical monsoon climate experiences warm temperatures throughout the year.
- An oceanic or highland climate, also known as a marine or maritime climate, is the Köppen classification of climate typical of west coasts in higher middle latitudes of continents, and generally features cool summers (relative to their latitude) and cool winters, with a relatively narrow annual temperature range and
- Land in a rain shadow is typically very dry and receives much less precipitation and cloud cover than land on the windward side of the mountain range. Some examples of rain shadow deserts in North America include: The dry basins east of the Cascade Range in Washington and Oregon.
- Road closures, as well as power and communication outages are additional consequences of monsoon weather hazards.
- Flash Floods.
- Downburst Winds.
- Thunderstorms and Dust Storms.
- Extreme Heat.
