100
The type of cloud that is associated with periods of long, steady heavy rain or snow.
What are nimbostratus clouds?
100
The relative humidity of air at 40 degrees C that contains 45 g/m3 of water vapor.
What is 90%?
100
The type of front that stalls or does not move for hours or days.
What is a stationary front?
100
Draw the symbol on a weather map for a cold front.
100
A comparison of the amount of water vapor in the air to the amount of water vapor needed for saturation.
What is Relative Humidity?
200
The characteristics of air located at high pressure.
What is dry, descending, cool, dense air?
200
The relative humidity of air at 25 degrees C that contains 7 g/m3 of water vapor.
What is 32%?
200
The type of air mass that would be considered warm and moist.
What is a mT airmass?
200
Draw the symbol for a stationary front.
200
Describe how clouds form.
What is from warm, rising air that cools as it rises and allows water to condense into clouds?
300
Type of precipitation that occurs when snow falls through a small warm layer and freezes before reaching the surface.
What is sleet?
300
Air at 15 degrees C has a RH of 100%. If the temperature rises to 20 degrees C Is the dew point reached?
What is NO the dew point will not be reached if the air temperature rises because warm air can hold more water vapor than cold air?
300
Describe TWO factors that would help you identify a cold front?
What are cold air advancing, steep slope of front, cumulonimbus clouds, and thunderstorms?
300
The type of weather associated with high pressure.
What is fair weather?
300
Describe how an air mass gets its properties.
What is air masses get their properties based on the area that they form over?
400
The rotation of air around a low pressure system moves in this way in the northern hemisphere.
What is inward (towards the low) and counterclockwise?
400
Air at 35 degrees C has a RH of 30%. If the temperature drops to 20 degrees C. Is the dew point reached?
What is No, dew point is not reached (11.1 < 15).
400
The type of air mass that would contain the least amount of water vapor and explain why.
What is a cP air mass because continental air is dry and polar air is cold so it can hold less moisture?
400
A city that is ahead of a cold front experiences warmer temperature and cloudy skies. This is what happens at that city as the front passes through.
What is as the front approaches it begins to rain and as the front passes the temperature drops, the rain begins to stop, and skies will begin to clear?
400
A wind vane that is pointing to the north northeast indicates a wind coming from this direction.
What is the north northeast?
500
Describe the type of air that would allow the most water vapor to evaporate into it.
What is the air is DRY and WARM? (*Wind will help speed up the evaporation!*)
500
Air at 25 degrees C has a RH of 70%. If the temperature drops to 20 degrees C. Is the dew point reached? What is the new Relative Humidity?
What is Yes, dew point is reached (15.4 > 15). The new relative humidity is 100%.
500
Describe TWO factors that would help you identify a diagram of an occluded front.
What are warm air cut off from the surface, cold air advancing towards cool air, clouds forming where the warm air is aloft?
500
The current type of weather associated with a city ahead of a warm front.
What is cool temperatures and long periods of steady rain or snow?
500
When condensation, such as dew, forms the water comes from here.
What is the water comes from the air?
