Weather Instruments
Measures air temperature
What is a thermometer?
The BOUNDARY where TWO UNLIKE --temperature (warmer or cooler)and humidity (warmer holding more humidity and cooler holding less humidity) --AIR MASSES meet or collide and where the weather occurs is called ... (remember there are 4 types of these)
What is a front?
This air pressure system has less dense air that rises and rain or storms are associated with it. Feel down in the dumps because clouds were created and no more clear weather... ):
What is a low pressure system?
An air mass that can be described as cold and moist.
What is maritime polar?
A huge body of air that has similar temperature, humidity at any given height.
What is an air mass?
Measures wind direction
What is a wind vane?
Swirling center of air that is moving counterclockwise- the wrong way, has low pressure and often associated with storms and precipitation.
What is a cyclone?
These lines on a weather map show that any location on the same line have the same temperature.
What is an isotherm?
An air mass that can be described as warm and dry.
What is continental tropical?
A cold air mass takes over a warm air mass, the cold air slides under the warm pushing the warm air up quickly bringing strong thunderstorms and heavy rains often with cooler temperatures afterwards.
What is a cold front?
Measures wind speed
What is an anemometer?
This pressure system has clear weather associated with it because the cold air is sinking and not creating clouds.
What is high pressure?
This weather front symbol has blue triangles that point in the direction the air mass is moving.
What is a cold front?
An air mass that is warm and moist.
What is maritime tropical?
Occurs when a warm air mass takes over a cold air mass when the warm air rises over the cold air mass creating clouds. The first cloud that signals this front is on the way is the cirrus. This front brings a few days of gentle rain.
What is a warm front?
Measures air pressure
What is a barometer?
This happens when warm air rises --and of course it holds water vapor-- bc it has space because warm air is less dense than cooler air--- then this water vapor Cools into water droplets (liquid) creating Clouds so this process is called the the 3rd C...
What is an condensation?
The variable in an experiment that the scientist changes to see what results is called (I the scientist)
What is the independent variable? MIX
An air mass that is cool and dry.
What is continental polar?
A stalled front (neither the warm air mass nor the cold air mass is dominating) and usually brings many days of clouds and precipitation.
What is a stationary front?
Measures relative humidity
What is a hygrometer/psychrometer?
This type of air can holds more water vapor because it is less dense with the molecules spread out farther apart making space for the water molecules to fit- it is known as thin air like in the thermosphere.
What is a warm air?
The variable that we measure because it is the response/result in an experiment is called.
What is the dependent variable (DRY)
An air mass that forms over the states of Arizona and New Mexico in the southwest would be a _______________air mass.
What is continental tropical?
A cold air mass overtakes a warm air mass which has a cold air mass behind it, the 2 cold air masses squeeze the warm air mass off the ground.
What is an occluded front?
