shows storm systems

Occluded front

2 cold fronts move in and lift a warm front, brings heavy winds and rain

Stationary front

wind blows in opposite directions, brings steady rains

What do warm fronts bring?

slow, steady drizzle

What do cold fronts bring

heavy rain, thunderstorms

What are isobars

connects pressures, forms concentric circles

What are isotherms?

connects temperatures and forms parallel lines

What is the Coriolis Effect

curves the winds

How is wind speed determined?

the pressure gradient

What is low specific heat?

requires little energy and cools quickly

What is high specific heat?

requires lots of energy

characteristics of maritime

moist weather

characteristics of continental

dry temperatures

characteristics of tropical

warm temperatures

what is conduction

contact heat between atoms

what is insolation

energy from the sun

what is convection

energy transferred due to density differences
