What causes weather conditions in an area to form tornadoes? The air near the ground must be hot and humid. A cool air mass must be in the atmosphere as the hot and humid air rises. Strong winds must be blowing in the atmosphere causing wind shear and the air to spin....
Where are the trade winds located? What is the prevailing wind direction in North America? What are isobars in meteorology? What is a floodplain zone? Does wind shear form large hail? What are subtropical jet streams? What is the average wind speed of a tropical storm?
How does a mesocyclone form within a supercell thunderstorm? What type of weather is associated with cirrus clouds? What clouds have the greatest turbulence? What is used to classify tornadoes? What is a supercell in a hurricane that causes tornadoes?
Eventually, there's enough spiraling energy to create a vortex. Vortices are a common phenomenon. After all, you see them in tubs and sinks all the time. Small dust devils sometimes form when winds flow over hot deserts, and wildfires can also produce climbing vortices of flame and ash ...
This rotation increases the storm's energy and causes an eye to form - a vertical axis of warm, rising air. Then, winds blowing high above the Earth's surface set the storm on its path, many times towards land. The hurricane is nature's most massive storm. Hurricanes cause a lot of ...
They play a part in steering the flow of tropical cyclones that develop above the world’s oceans. Also, trade winds direct the direction of African dust westward across theAtlantic Oceaninto the Caribbean Sea, and some parts of southeast North America. ...
26, eight other named storms have formed in the Atlantic. Five of the season's storms have been hurricanes. What are hurricanes? Hurricanes are tropical cyclones. When a tropical cyclone's sustained winds reach 39 to 73 mph (63 to 118 km/h), it is considered a tropical storm and it ...
【题目】In the second half of each year, many powerful storms are born in the tropical (热带的)Atlantic and Caribbean seas. Of these, only about half a dozen becomes the strong, circling winds of 75 miles per hour or more that are called hurricanes, and several usually make their way to...
A lowered water table can be devastating for farmers who can't keep crops alive in such dry soil [source: USA Today]. On the other hand, deforestation can also cause flooding. Coastal vegetation lessens the impact of waves and winds associated with a storm surge. Without this vegetation, ...
Street and park trees often endure harsher conditions, including increased temperatures and drier soil and air, than those found in urban or natural forest
