Quick FactsMeteorology
– The study of the atmosphere and weather
What is the main cause for any type of wind on Earth?– Uneven heating and Pressure Gradients
What causes Global Winds?– Global Convection Cells
Why do weather patterns move in predictable directions across the country?
– Prevailing Winds caused by Coriolis Effect
What is the name for a boundary between Air Masses?– Front

Mid Latitude Low Pressure SystemsAn important weather pattern that occurs over and over again with
predictable and sometimes devastating effects to distribute atmospheric energy and moisture in a predictable pattern

What we discussed today• Meteorology is…
– Study of the atmosphere and weather.
• Stationary Fronts are…– A boundary between a cold and warm air mass where neither front is advancing, but the
air masses may slide past one another.
• Occluded Fronts are…– A location at the center of a low pressure system where a warm air mass is squeezed
between an advancing cold front and preceding cooler air, and precipitation often occurs.
• Cyclogenesis is…– The formation of a Mid-Latitude Low Pressure system.
• Mid Latitude Lows are…– An important weather pattern consisting of a large rotating low pressure
centers with predictable effects that distributes atmospheric energy and moisture across large portions of our country.
