Hurricane & Weather Forecast Flashcards
On the hurricane WebQuest, what happened to wind speed in Hurricane Katrina as the pressure dropped?
When air pressure decreases, wind speed increases.
What type of weather change does a cold front bring?
A cold front brings heavy rain, storms, and cooler temperatures.
What type of weather changed as I warm front bring?
I warm front bring steady precipitation and warmer temperatures.
How do you know the direction I 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 hurricane when it moves Over land?
It gets weaker.
What happens to a hurricane when it moves warm ocean water
It gets stronger or faster
What happens to her Kay when it moves over cool ocean water
It gets weaker
Why does a hurricane not continue to gain strength as it moves Northeast in the Atlantic Ocean
The water is cooler in the north Atlantic.
What is the difference between westerlies and easterlies (tradewinds)?
Westerlies blow from the west to east and cause hurricanes to turn away from the United States. Trade winds blow hurricanes from east to west toward the United States.
What is the latitude line that divides the trade winds from the westerlies?
30° 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
List the order a storm grows to become a hurricane in order from weakest to strongest.
Tropical disturbance, tropical depression, tropical storm, hurricane (category 1–5)
Using the Saffir – Simpson scale, what category hurricane occurs when windspeeds reach 115 mph?
Category three
Predict where the hurricane will most likely hit land 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
Why doesn’t a hurricane form near the equator
The Coriolis effect is not strong enough to cause the storm to rotate
