Air Masses and Fronts
A huge body of air that has similar temperatures, humidity, and air pressure throughout it is called a
air mass
A violent disturbance in the atmosphere
Storm
A sudden, violent flood that occurs within a few hours or even minutes of a storm
flash flood
scientist who study the causes of weather and try to predict it.
meteorologist
When a warm air mass collides with a slowly moving cold air mass bringing widespread rain.
warm front
Warm air mass that forms in the tropics and has low air pressure
tropical
The type of cloud that produces thunderstorms and tornadoes
cumulonimbus
First rule in flood safety.
Go to higher ground
lines joining places on the map that have the same air pressure.
isobar
When two cold air masses cut off a warm air mass pushing it up.
Occluded Front
A cold air mass that forms north or south of 50 deg. latitude
Polar
a sudden spark, or energy discharge
lightning
Three hazards created from floods
downed electrical poles, polluted water, landslides or mudslides, emergency vehicles can not get to you
lines drawn on a map connecting places of equal temperature.
isotherms
When a cold and warm air mass meet, but neither one has enough force to move the other
Stationary front
A humid air mass that forms over oceans.
Maritime
a rapidly whirling, funnel-shaped cloud that touches the surface. Creates the strongest winds.
Tornado
Occur when so much water pours into a stream that it overflows its banks
flood
A weather event where trade winds weaken around S. America and change the global weather patterns
El Nino
When a cold air mass runs into a slowly moving warm air mass bringing quick storms.
cold front
A dry air mass that forms over land
Continental
A tropical spinning storm that occurs from June-November.
Hurricane
The goal of issuing flood watches and warnings
To get people to evacuate!
A device used to collect data from the upper troposphere and stratosphere.
weather balloon
