1.Which condition is believed to be caused by El Niño and effectively weakens hurricanes in the Atlantic ocean?
*warm water temperatures
*high wind shear
*low wind shear
*high pressure
2.We only see hurricanes in the summer months because
*there is more rain in the summer.
*the winds are calmer in the summer.
*the water is saltier in the summer.
*the water is warmer in the summer.
3.Hurricanes in the Northern hemisphere always rotate:
*counter-clockwise
*clockwise
*there is no rotation due to the Coriolis effect
4.Check the boxes below that indicate possible damaging effects directly caused by a hurricane:
*low waves
*high winds
*tornadoes
*rip tides
*fires
*wind shear
*coastal flooding
5.Which of the following conditions describes the eye of a hurricane? Check all that apply.
*low pressure
*high pressure
*high winds
*calm winds
*higher water levels
*lower water levels
6.Which of the following lists the four steps of hurricane development in the proper order?
*area of low pressure, hurricane, tropical storm, tropical depression
*area of low pressure, tropical depression, tropical storm, hurricane
*tropical depression, area of low pressure, tropical storm, hurricane
*area of low pressure, tropical storm, tropical depression, hurricane
7.Explain what the difference is between a hurricane watch and hurricane warning.
8.Explain how a storm surge forms and what effect this can have on the coastline.
9.Explain why hurricanes cannot form along the equator.
3 answers
1. High wind shear
2.The water is warmer in the summer
3. Counter-clockwise
4. High winds, tornadoes, riptides, coastal flooding
5. Low pressure, calm winds, higher water levels
6. Area of low pressure, tropical depression, tropical storm, hurricane
7. A hurricane watch announces that hurricane conditions are 'possible' within the specified area, whereas a hurricane warning announces that hurricane conditions are 'expected' within the specified area. A hurricane watch will be issued 48 hours in advance of the anticipated arrival of tropical-storm-force winds whereas a hurricane warning will be issued 36 hours in advance. Both are announced a considerable time before hand because when the winds reach tropical-storm-force, it becomes more difficult to do outside preparedness-activities.
A hurricane/weather watch lets people know that weather conditions are favorable for a hazard to occur. During a weather watch, information is gathered and analyzed in order to raise awareness for any coming threats, hazards, or risks, It will allow people to prepare and plan in advance to be protected.
On the other hand, a hurricane warning requires immediate action. Meaning that the weather hazard is either going to happen very soon at any moment, or is already happening. In case of such events, it is important to have an emergency kit and medical supplies ready in advance and at hand as you head to a safe place. Both hurricane/weather watches and warnings are important, but warning are important as they require immediate action.
8. Storm surge is water that is pushed toward shores through the force of winds swirling around the storm. Normal tides combined with the advancing surge creates the hurricane storm tide, which raises the average water levels. Depending on the force of the winds (and the slope of the continental shelf), water levels may raise to 15 feet or higher than normal.
The rise in water levels can cause severe flooding in coastal areas (especially when there are normal high tides). Many people live among low-lying coastlines in the US, therefore it is very dangerous. It also damages ships, marinas, and boats.
9. Hurricanes cannot form along the equator due to the lack of Coriolis Force, which is the force that causes the cyclone to spin.
