Which layer of the atmosphere does weather occur? Troposphere relative humidity The amount of water vapor in the air compared to the amount of water vapor the air can actually hold. How do you measure relative humidity? Psychrometer air pressure Weight of the air What causes differences in air pressure? Humidity and Temperature What is an air mass? A body of air with temperature, humidity, and pressure. What determines the conditions of an air mass...

Air Mass a body of air with horizontally uniform temperature, humidity, and pressure. Tropical of, typical of, or peculiar to the tropics. Continental An air mass that is formed over land. Polar Air masses that are cold and from up in the poles. Maritime Air Mass that form over water or it has to do with water. Prevailing Westerlies winds from the east toward the west in the middle latitudes between 30 and 60 degrees latitude. Jet Streams a narrow...

ATSC 113 Fly Final Review Exam Questions and Answers If CAPE (Convective Available Potential Energy) were large (> 2000 J/kg) then you could anticipate that the following factor might affect your flight: - Strong thunderstorms are likely - Turbulence could be weak in clouds - Being near a cost line - There is a coating of ice that acts like a cape over your wings - Air is statically stable - Answer-Strong thunderstorms are likely The weather associated with occluded fronts is most ...

ATSC Learning Goals question and answers graded A+ 2023 updated1a. Identify & classify clouds, and relate them to local and larger-scale weather systems and to potential hazards to aircraft - correct answer Clouds can be normal or special. There are two types of normal clouds. Cumuliform (connective clouds) are puffy and associated with updrafts Form when humid air rises through cooler air This can occur when the air at the ground is colder than the surface (ex. Air above the ocean is...

A continental tropical air mass formed over the Southwest U.S. This area is called its _____. home region mass region source region front region source region Select all of the answers that apply. Which of the following characteristics must an air mass have? It must be 1,000 miles or more in size. It has different temperatures but uniform humidity. It flows as one unit. It must form over a low-pressure area. It has a uniform temperature and humidity. It must be 1,000 miles or ...

Air Mass -an extremely large body of air whose properties of temperature and humidity are fairly similar in any horizontal direction at any given altitude -a single air mass may cover more than a million square kilometers Source Regions -extensive areas of essentially uniform surface conditions over land or water, typically of large-scale air subsidence and lateral divergence, where air masses develop their initial properties How are air masses classified? -according to tempera...

What are the four types of air masses and where does each form? Polar forms over cold areas, tropical forms over warm areas, continental forms over land, and maritime forms over the oceans. What are four types of fronts? Cold front, warm front, occluded front and stationary front. What happens during a cold front? A cold air mass pushes and replaces a warm air mass. What kind of weather can happen at cold fronts? Heavy rain or snow, cloudy skies or thunderstorms. ...
