Weather

_____ degrees latitude and ______ degrees latitude are both high pressure areas on the globe.

30 and 90 degrees North or South

All winds are named by the _____________ from which they blows from.

Direction

Cold Front

When a cold air mass invades a warm air mass, causing high winds and thunderstorms.

Occluded front

When a cold front catches up to a warm front causing high winds and heavy rain (sometimes severe weather).

Front

A boundary between 2 air masses with different temperatures, density, or moisture.

Cold Front

Continental Polar Air Mass

Cold and dry air from the continents near the poles (Canada).

Maritime Polar Air Mass

Cool and moist air from ocean near the poles.

Explain the Coriolis Effect and the direction the winds are deflected in the northern and southern hemispheres.

Coriolis effect is the apparent deflection of winds and objects moving long distances in the sky due to the rotation of the Earth. Northern hemisphere deflects to the right, while Southern hemisphere deflects to the left.

Areas of ______________ Pressure will typically have cooler temperatures but clear skies because the air is cold and does not rise to form clouds.

High Pressure

Explain the relationship between density, pressure and temperature of air.

High temperature, low density, Low pressure Low temperature, High density, high pressure

Continental Tropical Air Mass

Hot and dry air from land masses near the equator (Mexico).

Name the breeze that happens at night.

Land breeze happens during the night because the water cools off and heats up more slowly than the land. So the air above the water is warmer (low pressure) so it rises. The air above the land is cooler (higher pressure) so it sinks. Wind blows from land to sea at night.

Air Mass

Large body of air that takes on the temperature and humidity of the surface below.

Areas of _____________ pressure will typically have cloudy skies and warmer temperatures because the air is warmer and will rise forming clouds.

Low Pressure

Name the three different global wind patterns and that latitude ranges the exist

Northeast and Southeast trade winds are between 0 - 30 degrees latitude go from east to the west. Westerlies between 30-60 degrees blow from west to east. Polar Easterlies between 60-90 degrees blow from east to the west .

Name the breeze that happens during the day.

Sea breeze happens during the day because the land heats up faster than the water. The air above the land is hotter (lower pressure) so it rises. The air above the water is cooler (higher pressure) so it sinks. Wind blows from Sea to the land.

Explain how the specific heat of land and water causes land and sea breezes.

Specific heat is the amount of energy it takes for a 1 gram of a substances to heat up 1 degree Celsius. Since it takes less energy to heat up land than water, land heats up and cools down more quickly. This causes the air above the land to be hotter during the day and cooler at night.

Describe the Ferrel Cell.

The Ferrel cell rises at 60 degrees North diverts toward the equator and cools off in the upper atmosphere. It sinks at 30 degrees North or South.

Describe the Hadley Convection Cell.

The Hadley convection cell rises at the equator, diverges toward the poles cools off in the upper atmosphere and sinks at 30 degrees north or south.

Explain how the Sun is responsible for all weather on Earth.

The Sun is responsible for all weather on Earth because it heats our Earth through radiation. The Earth heats unevenly due to it being spherical and the fact that land and water heat up and cool down at different rates (specific heat).

Conduction

The direct transfer of heat from one substance to another substance that it is touching (molecules bumping into each other) in solids.

Describe the Polar Cell.

The polar cell rises on 60 degrees north is diverted toward the poles and sinks at 90 degrees North or South.

Radiation

The transfer of energy by electromagnetic waves, such as light and microwaves

Convection

The transfer of heat by the movement of a fluid (liquids and gases).

Warm Front

Maritime Tropical Air Mass

Warm and moist air from the oceans by the equator.

Stationary front

When a warm air mass and a cold air mass meet and no movement occurs. They linger for days causing some precipitation, little wind, and overcast skies.

Warm Front

When a warm air mass invades a cold air mass, causing moderate to light rain.

_______ degrees latitude and __________ degrees latitude are both low pressure areas on the globe.

Zero and 60 degrees North or South

Which latitude on the globe represents the lowest air pressure?

Zero degrees latitude (equator) because this is the warmest area on the earth because it receives the most direct sunlight.
