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.Know More
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
The sun creates a wave of pressure that hits low points twice a day, one of which occurs a couple hours before sunrise, and this reduction in pressure often results in lower air temperature. This wave is called the solar semidiurnal tide.Full Answer >
The average temperature of the Arctic Circle ranges from minus 58 degrees Fahrenheit to 86 degrees Fahrenheit. During the summer months, the average temperature at the Arctic circle is approximately 50 degrees Fahrenheit in certain locations.Full Answer >
A rainbow is an optical illusion caused by water droplets reflecting, refracting and dispersing light, causing a prismatic representation of the color spectrum to appear in air. Rainbows can be single, also known as a primary rainbow, or they can be double.Full Answer >
Spring tides occur twice each lunar month, at new moon and at full moon. At these times, the sun, moon and Earth are nearly aligned, which increases gravitational pull on the oceans and results in higher-than-average high tides and lower-than-average low tides.Full Answer >
