(1) _______ is the amount of water vapor in the air. How much water the air will hold depends on (2) the air temperature. Air is _______ when it holds as much water _______ as possible. It is
(3) measured in _______ of water/cubic _______ of air (g/m3).
(4) Relative humidity measures the amount of _______ _______ in the air as a percentage of the
(5) saturated amount (_______ amount it can hold). If the relative _________ is 100% it will likely (6) rain or form ____________. The dew point tells you the __________ when saturation reaches (7) 100%. Warmer air can hold _______ water vapor.
(8) Air pressure is the ____ that is exerted on a surface by the weight of ____. The two types of air (9) pressure systems that impact our weather are _______ -pressure systems and _____-pressure
(10) systems.
(11) A high-pressure system brings sunny, ____ days. This is because the _______ air moves away (12) from the center of the area and the air above _______ towards the surface. Surface
(13) temperatures are warmer so as the air sinks it _______ __and water _______ in the clouds
(14) evaporate.
(15) A low-pressure system brings clouds with the potential for _____ or _____ (depending on the (16) temperature). Surface air moves _____ a low pressure area from all sides. The incoming air (17) meets in the center and ____. As it rises, it gets _____ and water vapor condenses into _____ (18) _____, which form clouds. Low pressure systems over warm ocean or gulf waters can result (19) in a _____.
(20) An air mass is a large body of air. Air masses can have different _____ ___and amounts of (21) ________. They are named based on where they form.
(22) A continental air mass forms over land and is __. If it (23) forms over a cold location, it is a continental polar air
(24) mass. If it forms over a warm desert it is a continental (25) tropical air mass. An air (mass that forms over the
(26) Arctic is a _____ _____ air mass (very cold).
(27) Maritime air masses form over _____ and have a lot (28) of (moisture in them. Just as with continental air
(29) masses, they can form in _____ or warm locations. A
(30) maritime _____ air mass forms over a cold area and a
(31) maritime _____ air mass forms over a warm location.
(1) Humidity is the amount of water vapor in the air. How much water the air will hold depends on
(2) the air temperature. Air is saturated when it holds as much water vapor as possible. It is
(3) measured in grams of water/cubic meter of air (g/m3).
(4) Relative humidity measures the amount of water vapor in the air as a percentage of the
(5) saturated amount (maximum amount it can hold). If the relative humidity is 100% it will likely (6) rain or form precipitation. The dew point tells you the temperature when saturation reaches (7) 100%. Warmer air can hold more water vapor.
(8) Air pressure is the force that is exerted on a surface by the weight of air. The two types of air (9) pressure systems that impact our weather are high-pressure systems and low-pressure
(10) systems.
(11) A high-pressure system brings sunny, clear days. This is because the sinking air moves away (12) from the center of the area and the air above descends towards the surface. Surface
(13) temperatures are warmer so as the air sinks it warms up and water droplets in the clouds
(14) evaporate.
(15) A low-pressure system brings clouds with the potential for rain or storms (depending on the (16) temperature). Surface air moves towards a low-pressure area from all sides. The incoming air (17) meets in the center and rises. As it rises, it gets colder and water vapor condenses into water droplets, which form clouds. Low-pressure systems over warm ocean or gulf waters can result (19) in a hurricane.
(20) An air mass is a large body of air. Air masses can have different temperatures and amounts of (21) moisture. They are named based on where they form.
(22) A continental air mass forms over land and is dry. If it (23) forms over a cold location, it is a continental polar air
(24) mass. If it forms over a warm desert it is a continental (25) tropical air mass. An air mass that forms over the
(26) Arctic is a continental Arctic air mass (very cold).
(27) Maritime air masses form over oceans and have a lot (28) of moisture in them. Just as with continental air (29) masses, they can form in cold or warm locations. A (30) maritime polar air mass forms over a cold area and a (31) maritime tropical air mass forms over a warm location.
