Thank you for all your great questions from my first post. A lot of you seemed interested in Hurricanes. Well, today I will be talking more about Hurricanes.
WHAT EXACTLY CAUSES HURRICANES?
Hurricanes start when moist air from the ocean surface begins to rise rapidly, where it encounters cooler air that causes the warm water vapor to condense and to form storm clouds and drops of rain. The condensation also releases latent heat, which warms the cool air above, causing it to rise and make way for more warm, humid air from the ocean below. As this cycle continues, more moist air is drawn into the developing storm and more heat is transferred from the surface of the ocean to the atmosphere. This continuing heat exchange creates a wind pattern that spirals around a relatively calm center, like water swirling down a drain. So, mosit air and warm water mainly causes Hurricanes. That is also why hurricanes start in the tropics.
WHAT ARE THE EFFECTS OF HURRICANES?
When a hurricane strikes a coastal area, it brings a number of serious hazards which include heavy rains, high winds, a storm surge, and even tornadoes. Storm surge pushes seawater on shore during a hurricane, flooding towns near the coast. Heavy rains cause flooding in inland places as well.
IS HUMAN ACTIVITES CAUSING HURRICANES?
Yes, it is. In fact, human activity is making Hurricanes much worse. One example is that sea levels have already risen because of global warming, and those heightened sea levels make storm surge levels higher, pushing more water onto land and creating even more flooding. The most important problem is: we are causing severe climate change that causes serious weather events. However, human still didn't care and continued to cause climate change, which eventually leads to more extreme weather events. So, I strongly encourage you to help stop global warming and climate change to decrease the possibilites of severe weather events in the future.
WHAT ARE THE DIFFERENCES BETWEEN HURRICANES AND TORNADOES?
The difference is that a tropical storm has wind speed up to 73mph, once it exceeds this then it become a hurricane.Tornadoes are usually very short and can last up to an hour, but a hurricane can last up to three weeks. A hurricane almost always forms over sea while a strong tornado usually forms over land.
