As earth revolves around the sun the northern hemisphere is titled
Toward the sun in June but away from it in December
The primary reason that the polar ocean doesn’t freeze solid and the equatorial ocean doesn’t boil away is because the
Ocean moves heat from the low to the high latitudes
A cyclone is
A huge rotating made of low pressure air in which winds converge and ascend
Coriolis effect is caused by the
Different speeds at which points at different latitudes move
The greatest destruction of a hurricane is caused by
Storm surge. Mass of water driven by the storm 1 meter in open sea
Doldrums
Calm equatorial areas where the winds of two Hadley cells converge
The Coriolis effect
Eastward rotation of wary on its axis deflects the moving air or water (or any moving object that has mass) away from its initial course
The long term average of weather in any area is
Climate
To qualify as a hurricane a tropical cyclone must have winds of at least
119 kilometers 74 mph
In air as temperature increases water decreases. as water content increases density
Decreases
As air rises, it expands and cooks; as air falls it
Compresses and heats
Coriolis deflection is to the right in the northern hemisphere and to the
Left in the south
Warm air expands and rises at equator
Falls and cools at poles
As air rises at the equator it loses moisture by
Precipitation
Hadley cells
A pair of cells in the tropics on each side of the equator
