What is What is Weather?Weather?• The state of the

atmosphere with respect to wind, temperature, cloudiness, moisture, pressure.

• Short Term– Days– Weeks– Months

AtmosphereAtmosphere

The gaseous envelope surrounding the earth; the air.

LowLow PressurePressure• Air rises in low

pressure systems

• When the air rises it condenses into clouds and rain, snow, sleet.

Rain Rain andand Storms Storms

Rain and storms are the result of a low pressure system.

CloudsClouds

Increased water vapor creates clouds during a low pressure system

High Pressure• Often occurs when there is uneven

heating of the ground.• Causes the hot air to rise and spread

out.• Associated with clear, cool weather.• Can cause “cold snaps”

– Unseasonably cold and sunny weather are observed.

• Clear skies are indicative of a high pressure system
