FC: Weather Booklet by Eric Fortenberry

1: Air Pressure and Density Gravity is what causes pieces of the air to fall to earth the air above exerts a force on the air below air pressure is the greates and stronges closer to earth density and temperatures relationship is called inversely proportional

2: Jet streams and Air Masses the difference in temperature pressure and density causes jet streams and air mass is a massive body of air that looks like the area that it is over

3: Classifying Air Masses & Air Mass Modification there are 5 types of air masses they are continental tropical, marititme tropical, continental polar, and maritime polar air masses tend to move around alot and like jet streams the tend to take on the shape of their new area

4: Fronts ( Warm and cold ) a cold front is where a warm ai mass collides with a cold air mass a warm front happens when a cold air mass is overtaken by a warm air mass

5: Fronts (Stationary & Occluded ) when two air masses colide and stall this is called a stationary front these fronts are mainly warm when a cold air mass overtakes a warm front is a occluded front these fronts bring strong winds and heavy percipitation

6: Pressure systems High Pressure Systems they move in a clockwise direction they usually bring fair weather Low Pressure Systems they move in a counter clockwise direction and they usually bring rain

7: Wind systems trad winds which are located at 30 degrees north and south latitude move westward towards the equator these winds include the doldrums prevailing westerlies these winds are located between 30 - 60 degrees north and south latiudes these winds greatly affect the movement of weather polar easterlies these winds are found at 60 degrees latitude and the poles they blow cold air and they flow from the southeast to the northwest

8: Thunderstorms they develop when a cumulus cloud grows into a towering cumulonimbus cloud an air mass thunderstorm forms due to the unequal heating of the earths surface sea breze thunderstroms form in tropical and subtropical regions mountain tunderstorms form when air is lifted over a mountain frontal thunderstorms they usually rise as the result of a advancing cold front severe thunderstorms these storms can created devestating hail and tornadoes supercells are a extremely large thunderstorm with winds reaching speeds of 240km/h

9: Lighting, Hail, Tornadoes lighting is and electrical discharge caused by the rapid movement of air hail is rain that falls as ice rangeing in size and shape a tornadoe is a strong whirling column of air that touches the ground and causes major destruction

10: Tropical Cyclones they are some of the most powerful storms on earth these stroms get their energy from warm water they are also known as hurricanes strikeing mostly in the late summer and early fall they start out as a tropical depression then they move to a tropical storm and then they finally move to a hurricane

11: Hurricanes hurricanes are classified in 5 different catagories 1 and 2 being minimal to moderate damage 3 is considerd highly dangerous 4 and 5 are considered deadly hurricanes cause big waves called storm surges which are mounds of ocean water driven by winds
