1. WELCOME TO WEATHERGEEK WEATHER STUDY ZONE WEATHER STUDY ZONE Produced by WEATHERGEEK Produced by WEATHERGEEK

2. ENTERING THE STUDY ZONE PRESSURE H L High pressure this blue H means high pressure usually SUNNY SKIES/ CLEAR SKIES/ NICE WEATHER WIND FLOW AROUND A HIGH PRESSURE IS AS FOLLOWSH You will see Northerly winds out in front of the High and (clockwise all the way around). Low pressure this red L means low pressure usually CLOUDY/RAINY/DREARY/ NOT SO NICE WEATHER (Weatherman love to see the red L means that our job will be fun filled not so boring as with the blue H. WIND FLOW AROUND A LOW PRESSURE IS AS FOLLOWS L You will see Southerly winds out in front of the Low and (counterclockwise all the way around).

3. FRONTAL TYPES!!! FRONTAL TYPES THE COLD FRONT: The cold front its mission consist of bringing in colder air to the region its moving into. Usually replaces a warmer air mass. THE WARM FRONT: The warm front its mission consist of bringing in milder air to the region its moving into. Usually replaces a cool air masses. THE STATIONARY FRONT: This front can bring in either warmer or cooler air depending on which area influences your station. THE OCCLUEDED FRONT: This is when a area of Low pressure has bottomed out or should we say begins to dissipate two types you have warm/cold.

4. THE COLD FRONT IN ACTION The Cold Front in action: In the above diagram we see the cold front is dividing two stations. The following would be a example of possible weather these two stations could see. Station A(cold front has passed the station) Overcast Possible T-storms/slowly clearing/ Northwesterly Winds/Slowly increasing pressure Station B(in the warmer air mass in front of the cold front) Overcast T-storms/ Southwesterly Winds/Decreasing Pressure Sharp temperature changes Moisture Content Wind shifts Pressure changes Clouds/Precipitation A B

5. THE WARM FRONT IN ACTION The Warm Front in action: In the above diagram we see the warm front is dividing two stations. The following would be a example of possible weather these two stations could see. Station A(warm front has passed through the station) Showery/rapidly clearing/ Southwesterly winds/Slowly gradually increasing pressure Station B(in the cooler air in advance of the warm front) Showery precipitation / Northwesterly Winds/gradually decreasing in pressure Sharp temperature changes Moisture Content Wind shifts Slight pressure changes Clouds/Precipitation A B

6. THE TWO OCCLUDED FRONTS COLD OCCLUSION WARM OCCLUSION VERY COLD COLD WARM 1. 2. COLD WARM 3. COLD WARM COOL COLD WARM COOL COLD WARM

7. STATIONARY FRONT REMEMBER WITH THE STATIONARY FRONT NO MOVEMENT. # If at any time the warmer air Starts to dominate it will become A warm front. # If cold air dominates it will become A cold front. CP MT
