TEMS Science Weather This deck is for my weather exam in F period Science

Question Answer
What does cT stand for? Describe the air mass. cT stands for continental Tropical air mass. It forms over land, such as the deserts of northern Mexico and the southwestern United States. It brings clear, dry, and hot weather in the summer.
What does cP stand for? Describe the air mass. cP stands for continental Polar air mass. It forms over land, such as northern Canada, which brings extremely cold weather to the United States. In the summer, this air mass brings cool, dry weather.
What does mT stand for? Describe the air mass. mT stands for maritime Tropical air mass. It forms over warm areas in the Pacific Ocean. It brings hot and humid weather, hurricanes, and thunderstorms in the summer. It brings mild and often cloudy weather in the winter.
What does mP stand for? Describe the air mass. mP stand for maritime Polar air mass. It's cool and very wet. It forms over the North Atlantic Ocean.It brings rain and snow to the Pacific Coast in the winter and cool, foggy weather in the summer.
What geographic features affect our weather in Connecticut? Our nearness to the ocean affects our weather.
State the compostion of the atmosphere. The atmosphere is 78% nitrogen, 21% oxygen, and 1% is made up of argon, carbon dioxide, water vapor, and other gases.
Where is air pressure greatest? Why? Air pressure is greatest at Earth's surface because gravity pulling the molecules downward means there are more closer to Earth's surface. The lower the elevation, the higher the air pressure.
What are 2 factors that affect relative humidity? The amount of water vapor in the air and temperature.
When and where are breezes most likely to develop? Breezes form whenever there is a difference in temperature. They most likely form in a grassy area next to a parking lot.
What is caused by uneven heating of the Earth's surface? Breezes
Why does fog form over ponds/lakes on autumn mornings? Because fog forms when warm air flows over a cold surface, and in this case the pond/lake is the cold surface.
Describe the formation of a warm front. Warm air moves over cold, denser air. The warm air replaces the cold air.
What kind of weather is associated with a cold front? Thunderstorms, heavy rain, and snow.
Define convection The transfer of thermal energy by the circulation or movement of a liquid or gas.
Define thermal conduction The transfer of energy as heat through a material.
Define global warming A gradual increase in average global temperature.
Define The Greenhouse Effect The warming of the surface and lower atmosphere of the Earth that occurs when water vapor, carbon dioxide, and other gases absorb and re-radiate thermal energy.
Define radiation The transfer of energy as electromagnetic waves.
Define condensation The change of state from a gas to a liquid.
Define humidity The amount of water vapor in the air.
Define precipitation Any form of water that falls to the Earth's surface from the clouds.
Define runoff Water, usually from precipitation, that flows across land and collects in rivers, streams, and eventually the ocean.
Define evaporation Occurs when liquid water changes into water vapor, which is a gas.
Why is there such a marked difference in air temperature at the beach compared to Hartford? Because the Hartford is inland, and land heats up and cools off quicker than the beach area, which is water. At night, the land is cooler than the water, so the breeze moves to the water. During the day, its vice versa.
How does an on-shore breeze form? During the day, the water is cooler than the land and forms an area of high pressure. The breeze then comes from the water to the land, where the air is warmer and forms an area of low pressure. At night, it's vice versa.
How do changes in the amount of water vapor in the air affect relative humidity? At constant temperature and pressure, as the amount of water vapor in air changes, the relative humidity changes. The more water vapor there is in the air, the higher the relative humidity is.
Will air move from an area of high pressure to an area of low pressure or vice-versa? Air will move from an area of high pressure to an area of low pressure.
Describe local breezes Local breezes are caused by differences in area pressure due to local geographic features.
Describe local winds Local winds move short distances and blow from any direction. Local geographic features can produce temp. differences that cause local winds.
How do changes in temperature affect relative humidity? If the amount of water vapor in the air stays the same but the temperature changes, the relative humidity changes. The relative humidity decreases as the temperature rises and increases as the temperature lowers.
