What is the term for the moisture content of the air expressed as a percentage of the amount needed for saturation at that temperature?
-
Relative Humidity.
|
| 3103 |
What atmospheric conditions favor temperature inversion?

-
Temperature Inversion.
|
| 3105 |
What is the term for the decrease in temperature with increasing altitude in the Troposphere?
-
Normal Lapse Rate (approx. 6.5°C per 1,000 meters).
|
| 3106 |
What is the primary factor that causes the variation in temperature across latitudes?
-
Insolation/Solar Radiation.
|
| 3107 |
What are lines joining places having equal mean annual temperature called?
-
Isotherms.
|
| 3108 |
What is the term for the gradual rise in the Earth's average surface temperature?
-
Global Warming.
|
| 3109 |
What are the main Greenhouse Gases?
-
Water Vapor, Carbon Dioxide, Methane, and Chlorofluorocarbons (CFCs).
|
| 3110 |
What is the process by which the Earth's atmosphere traps the heat radiated by the Earth's surface?
-
Greenhouse Effect.
|
| 3111 |
Which surface has the highest albedo?
-
Fresh Snow or Ice.
|
| 3112 |
What is the term for the fraction of solar radiation reflected by a surface?
-
Albedo.
|
| 3113 |
What is the term for the energy radiated from the Earth's surface back into the atmosphere?
-
Terrestrial Radiation.
|
| 3114 |
What is the amount of solar energy received by a unit area at the outer limit of the atmosphere called?
-

-
Solar Radiation (Insolation).
|
| 3117 |
What is the primary difference between a Tropical Cyclone and a Temperate Cyclone?
-
Tropical cyclones form over warm oceans (no fronts), while temperate cyclones form over land or sea in mid-latitudes (involving fronts).
|
| 3118 |
What is the life cycle of a Temperate Cyclone described by?
-
The Polar Front Theory (by the Norwegian School).
|
| 3119 |
Where do temperate cyclones primarily form?
-
Along the Polar Front.
|
| 3120 |
What is the system of low pressure that forms in the mid-latitudes (35° to 65° N and S) due to the meeting of air masses?
-
Temperate Cyclone (or Extratropical Cyclone).
|
| 3121 |
What type of front forms when a cold front overtakes a warm front, lifting the warm air mass entirely off the ground?
-
Occluded Front.
|
| 3122 |
What type of front forms when the surface position of the front does not move?
-
Stationary Front.
|
| 3123 |
What type of front occurs when a warmer, less dense air mass replaces a retreating colder air mass?
-
Warm Front.
|
| 3124 |
What type of front occurs when a colder, denser air mass replaces a warmer air mass?
-
Cold Front.
|
| 3125 |
What are the four types of fronts?
-
Cold, Warm, Stationary, and Occluded.
