Meteorology Study Guide

What is weather?
The condition of the Earths atmosphere at a particular time and place.

Order the layers of the atmosphere
Troposphere, stratosphere, Mesoshere,

What is the basic division of the layers?
The pauses which are temperature differences

What happens in each layer of the atmosphere?
Troposphere- weather

How do winds form?
Unequal heating of the earths atmosphere

The two items that characterise air masses.
Temperature and humidity

What gas drives storm systems?
Water vapor

What is a front?
The boundary between two air masses

Cold front
Cold air moves into warmer air, rain cool temps thunderstorms

Stationary front
Neither air mass moves clouds and little rain

Occluded front weather
Warm air cought between cold air cloudy and rainy

What is humidity?

specific humidity
Amount of water vapor in the air

Three states of matter
Liquid, solid, gad

What is dew point?
The point when saturation occurs

What is air pressure?
Weight of all the air in the atmosphere pressing down on Earth

Why doea air have pressure?
Air has mass

As altitude increases, air pressure…

Three ingredients for cloud formation
Water vapor, cpndensation nuclei, cooling

Types of clouds
Cirrus, stratus, cumulus, cumulonimbus

Types of fog
Radiation fog and advection fog

What two items describe climate?
Temperature and precipitation

Why is our atmosphere important?

What is the greenhouse effect and how does it work?

Warm front
Warm air moves into cold air little rain, clouds, warmer temps

Relative humidity
Actual amount of water vapor in the air compared to the max amount the temp of the air can hold
