What are the three types of wind systems?
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10).
What are the 6 wind systems?
(In the Southern Hemisphere, low-pressure systems will be on your right.) The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums.
What type of seasonal wind brings heavy rains in the Philippines?
Monsoons MANILA, Philippines—Monsoons are seasonal winds that bring heavy rains. According to the Philippine Atmospheric Geophysical and Astronomical Services Administration, the country experiences two kinds of monsoons—the northeast monsoon and the southwest monsoon.
What are the 4 types of wind?
Types of Wind – Planetary, Trade, Westerlies, Periodic & Local Winds.
What are the wind systems?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
How do you think wind could be related to severe rainstorms?
Thunderstorms themselves are just reflections of currents of wind that move up, down, and around through our atmosphere. An upward moving air current that cools and condenses as it rises is what results in the thunderstorm forming.
What are the wind patterns called?
Global Wind Patterns: wind belts of the general circulation. The global wind pattern is also known as the "general circulation" and the surface winds of each hemisphere are divided into three wind belts: Polar Easterlies: From 60-90 degrees latitude. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies).
What causes heavy rainfall in the Philippines?
SOUTHWEST MONSOON SEASON IN THE PHILIPPINES The heavy rainfall during the southwest monsoon season is hypothesized as caused by strong convective activity generated by monsoon westerlies and enhanced by the presence tropical cyclone (TC) in the vicinity of northeastern Luzon.
What is amihan and habagat?
Habagat (southwest monsoon) is wind that brings heavy rainfall that results in floods during the wet season. Amihan (northeast monsoon) brings cold air to our shores from the Christmas season to February. These winds have been known to us for centuries.
What causes strong winds?
The Short Answer: Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure.
What is a strong wind?
Strong Breeze. 25 to 31 mph. Large branches in continuous motion. Whistling sounds heard in overhead or nearby power and telephone lines. Umbrellas used with difficulty.
What causes severe rainstorms?
When the temperatures become equal the air parcel will stop rising. The higher the air parcel rises in the troposphere, the more energy the air parcel will lose and the more condensation can happen. This leads to more severe rainfall.
What causes heavy winds?
Heavy winds are typically formed by atmospheric pressure variations, which cause gusts of air to rush in to fill low-pressure zones. Additionally, wind can result from heavy activity in the jet-stream high in the sky. Finally, large fronts of cold air can also provoke turbulence in the atmosphere.
What are wind systems?
Large global wind systems are created by the uneven heating of the Earth's surface. These global wind systems, in turn, drive the oceans' surface currents.
What causes heavy rainfall?
Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rain and snow storms.
What wind system brings heavy rainfall to the western coastal area of the Philippines?
SOUTHWEST MONSOON SEASON SOUTHWEST MONSOON SEASON IN THE PHILIPPINES The strong westerlies upon interaction with the mountain ranges along the west coast of Luzon produce strong vertical motion and consequently generate heavy rainfall.
What does Habagat bring?
Throughout the rest of the year, the Philippines experiences the west or southwest wind; south west monsoon, which in turn is referred to as the Habagat. The habagat season is characterized by hot and humid weather, frequent heavy rainfall, and a prevailing wind from the western parts.
What are strong winds called?
Gale. Gale refers to a current of air that measures in the range of 32 to 63 miles per hour on the Beaufort scale. More generally, it's any strong wind: On this links-style course, autumn gales blow fiercely across the moors – so fiercely that a misstruck shot can turn on you like a rogue boomerang.
What is another word for strong winds?
What is another word for strong wind?
| gale | cyclone |

How do you think wind could be related to severe rainstorms amplify?
Warmer temperatures would cause the air parcel to rise higher in the troposphere. The air parcel then loses more energy, causing more rainfall. Wind pushes air parcels even higher in the troposphere, where it is colder. The air parcels will then lose more energy and more rain can happen.
Why do some rainstorms have more rain than others?
When they get too large for the updraft to hold, they fall down as rain. Therefore, places where air rises more frequently get more rain, and it rains more heavily when the updraft is stronger.
What is a heavy wind?
"Damaging high wind" with sustained speeds greater than 58 mph, or frequent wind gusts greater than 58 mph. Damaging wind conditions are consistent with a high wind warning. High. "A High Threat to Life and Property from High Wind." "High wind" with sustained speeds of 40 to 57 mph.
What is called heavy rainfall?
It is defined as rainfall greater than 100 mm in 24 hours.
What is a heavy rainfall?
Heavy rain — when the precipitation rate is > 7.6 mm (0.30 in) per hour, or between 10 mm (0.39 in) and 50 mm (2.0 in) per hour. Violent rain — when the precipitation rate is > 50 mm (2.0 in) per hour.
What brings heavy rain to the Philippines?
summer monsoon The summer monsoon brings heavy rains to most of the archipelago from May to October. Annual average rainfall ranges from as much as 5,000 millimeters (197 in) in the mountainous east coast section of the country, to less than 1,000 millimeters (39 in) in some of the sheltered valleys.
What is Habagat wind?
Habagat is a major wind system which develops when it's summer in the northern hemisphere and winter in the southern hemisphere, said PAGASA Climate Monitoring Officer in Charge Annalisa Solis. Habagat winds blow from the southwest, hence its English name.
What are heavy winds called?
Gale. Gale refers to a current of air that measures in the range of 32 to 63 miles per hour on the Beaufort scale. More generally, it's any strong wind: On this links-style course, autumn gales blow fiercely across the moors – so fiercely that a misstruck shot can turn on you like a rogue boomerang.
How would you describe heavy wind?
For the wind, you can look into "gust" (noun), "blustery" (adjective), or their synonyms. The jacket flapping in the strong wind. swing, bounce, rock, sway, vibrate, flutter, wobble, oscillate, shake, wave, whip, be battered, flap, be agitated.
How did wind affect the amount of rain in the rainstorms?
Wind pushed the air parcel even higher in the air, in turn making the air parcel lose more energy. As we know, the higher the air parcel rises in the air, the more rain will occur than before, and even more severe storms.
What causes heavy rainstorms?
Climate change can affect the intensity and frequency of precipitation. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rain and snow storms.
