Hurricanes and Weather Flashcards
(19 cards)
what type of weather change does a cold front bring
A cold front brings heavy rain, storms, and cooler temperatures.
what type of weather change does a warm front bring
A warm front brings steady precipitation and warmer temperatures.
how do you know the direction a front is moving
The side that the symbol is facing.
what type of weather is associated with a high pressure system? Explain why.
A high pressure system brings clear weather because dry air is forced toward the ground.
what type of weather is associated with a low pressure system? explain why.
A low pressure system brings clouds and precipitation because air rises, cools, and condenses.
what happens to a hurricane when it moves over land
It gets weaker.
what happens to a hurricane when it moves over warm ocean water
It gets stronger (faster).
what happens to a hurricane when it moves over cool ocean water
It gets weaker.
why does a hurricane not continue to gain strength as it moves north east in the Atlantic Ocean
The water is cooler in the North Atlantic
what is the difference between westerlies and easterlies
Westerlies blow from the west to east and cause hurricanes to turn away from United States. Trade winds blow hurricanes from east to west toward the US.
what is the latitude line that divides the Tradewinds from the westerlies
30 degree North
List the five ingredients for a hurricane
warm ocean water, high humidity, converging winds, low wind shear, at least 300 miles from equator
what is the force that causes a storm to become a hurricane
Coriolis effect
why doesn’t a hurricane form near the equator
The Coriolis effect is not strong enough to cause the storm to rotate.
before a storm becomes a hurricane what is it called first
tropical storm
where is the order a storm grows to become a hurricane in order from weakest two strongest too strong
tropical disturbance, tropical depression, tropical storm, hurricane (Category 1-5)
using the Sapphire Simpson scale what category hurricane occurs when windspeeds reach 115 mph
Category 3
predict where the hurricane will most likely Atlanta and justify your answer using the following terms dividing line westerlies and easterlies
It will most likely hit Florida and turn back to the Atlantic because it is near the dividing line for westerlies and easterlies.
On the hurricane WebQuest, what happened to wind speed in Hurricane Katrina as the pressure dropped
When air pressure decreases, wind speed increases.
