Wind and weather Flashcards
How does a cold front form?
Cold air mass moving (pushing) under a warm air mass
How does a warm front form?
Warm air mass moving over a cold air mass
Convection
The transfer of heat through a gas or liquid as a result of particles moving from warmer areas to cooler areas
The Coriolis effect
The Coriolis effect is the rotation of the Earth under winds. As the Earth rotates, the winds appear to deflect, moving to the right in the northern hemisphere and to the left in the southern hemisphere.
Hurricane location
Northeast Pacific and Atlantic
Typhoon location
Northwest Pacific(coast of asia)
Cyclone location
South Pacific and Indian Ocean
Air Mass
An area with uniform pressure and temperature
Wind Belt
A permanent band of moving air that occur at set latitudes around the earth
Currents
The movement of a liquid or gas in a definite direction through a surrounding area.
Air is constantly moving in the Earth’s atmosphere, bringing weather to different parts of the Earth. What causes this constant movement of air?
High air pressure and low air pressure.
What are the short-term effects of volcano eruptions on the global climate?
The dust particles and gas released in the air reflect sunlight, causing the global temperature to go down short term.
What are the long-term effects of volcano eruptions on the global climate?
The dust particles come down and release CO2, but not enough, so the global climate returns to the same levels as before.
What are the two conditions that cause a hurricane to lose its strength?
Going on land, cold ocean water
How does a hurricane form?
Hurricanes form because of warm ocean water, which also creates humidity. This heats up the air around it, causing low air pressure. Then there’s a low air pressure center and high air pressure around it. This causes a full storm cycle to take place.
Is the eye of the hurricane calm or disastrous, and what type of air pressure is in the eye?
It’s calm and it’s low pressure
What’s a stationary front?
When a warm front and cold front meet but they can’t move past each other.
