Cyclones cause widespread flooding and wind damage. Flood damage results from the combination of torrential rain, which overwhelms the soil’s ability to absorb it, and storm surges, which force significant quantities of water up onto the shore in front of the storm. Wind damage results from the straight-line winds produced by the cyclone and tornadoes that the cyclone spawns.
Cyclones are large areas of very low pressure. They're often called hurricanes when they occur in the Atlantic Ocean and typhoons when they occur in the Pacific Ocean. When viewed from above, cyclones produce spiral bands of arms that radiate from a central vortex. Meteorologists name cyclones to avoid confusion when more than one low-pressure system exists in a single ocean basin. The names associated with particularly destructive or deadly cyclones are often retired when the storm dies.
To qualify as hurricane-force, winds must maintain speeds of 74 miles per hour or higher. Such speeds can topple trees and send small objects hurling through the air, where they can cause more damage. Some particularly strong hurricanes have produced wind speeds in excess of 200 miles per hour. Cyclones of such strength can blow houses off of their foundations and strip siding and shingles.Learn More
Unlike fresh water, which freezes at 32 degrees Fahrenheit, sea water freezes at 28.4 degrees Fahrenheit. The 3.6-degree difference in freezing temperature is due to the salt that is found in sea water, making it slightly more difficult to freeze.Full Answer >
The opposite of an ebb tide is a flood tide, according to The Fishing Line. The flood tide is the incoming water as the tide changes from low to high, and the ebb tide is the outgoing water as the tide goes from high to low.Full Answer >
While there are several characteristics of cold fronts, one of the most common is the drastic temperature differential cold fronts bring. Polar cold fronts have the potential to drop temperatures by 30 degrees Fahrenheit.Full Answer >
The bottom layer of the ocean is the coldest because cold water has a higher density than warm water. The colder water sinks to the bottom of the ocean. This movement of water creates the ocean currents.Full Answer >
