Weather Test Study Guide

2014-2015

THIS IS NOT EVERYTHING THAT CAN OR WILL BE ON THE TEST. YOUR NOTEBOOK IS A BETTER RESOURCE.

BUT THIS DOESN’T HURT TO DOUBLE CHECK.

THIS ALSO DOESN’T MAKE ANY CONNECTIONS FOR YOU, IT IS STRICTLY INFORMATION

Weather frontsWeather front conditions

Cold Cold air moves in and the air mass “takes over” the area. Warm air rises above the cool air (because its less dense). Cold front move more quickly than warm front and brings rainy and stormy weather.

Warm Moves slower, brings long periods of light/medium rain

Stationary A cold front and a warm front meet but do not have enough energy to collide. They are “stuck” in their place.

occluded When a cold front catches up to a warm front and forces the air upward so two cold fronts are next to each other

Weather forecasting -Using fronts, pressure systems and air masses to predict what weather will be like for certain areas based on these factors.-We practiced this in class on “The WeatherCycler”

Can you name where the High pressure areas are? Low pressure?Can you say where the fronts are AND what types?If you can can you PREDICT where the wind will come from in cities around the pressure systems? Can you Predict what the temperature will be like in certain area after some time has passed?(JUST ideas- not everything)

Severe Weather

Types

Tornado -come from thunderstorms-Fujita scale-Oklahoma is the “Tornado Capital”

Hurricane -winds over 75 mph-warm tropical water-center is called the “eye”-in Asia they are called typhoons

Thunderstorm -3 stages: cumulus, mature, dissipation-features: heavy rain, high winds, lightning, and hail-average time: 10-12 minutes
