This movement which is the result of air warming and cooling across the global
convection currents
Tropical storms form in these areas
warm ocean water
This air mass would most likely bring cool and dry weather to a region
cP or continental polar
The change in air pressure descreases as the altitude -
increases
What occurs in the eye of a hurricane
calm air
These are the 3 things that determine weather on a daily bases
the temperature of the air, the air pressure and amount of moisture in the air
This has rain, thunder and lightning.
Thunderstorm
a warm air mass colliding with a cool air mass might result in a
thunderstorm
To create convection currents, hot air _____ while colder air ____
rises and sinks
What are the characteristics of an Artic air mass
very cold and dry
The result of a low pressure system moving into an area currently experiencing high pressure
cold, cloudy and rainy
This can flood and damage homes due to strong winds and rain usually starting in the ocean and moving towards coastline cities.
Hurricane
An area of high pressure will most likely result in this type of weather
clear weather
1. high 2. low
What type of air mass is moist and warm
Tornadoes can form when two fronts do what?
move into one another
These might happen during a severe thunderstorm. They appear as a a rotating winds going down from the clouds in a funnel until they touch the ground.
Tornado
What is a large body of air that is uniform in characteristics such as temperature and humidity?
an air mass
Warm air rises because it has ____ density than cool air
lower
Formed when warm and moist air rapidly rise
Thunderstorms, Tornadoes, and Hurricanes
If a martime tropical air mass moves into a maritime polar air mass, what type of front is created
warm front
These occur over ocean water, where it is warmest
Hurricane
What happens when warm, moist air moves inland over hot, dry land?
warm air rises, causing water vapor to condense and form clouds
Where does the energy that powers a hurricane originate?
warm, moist air
What factor would increase the chance that a severe thunderstorm would occur?
increased surface moisture
