With increase in global temperatures, the rainfall associated with cyclones would

Hurricanes that affect the US usually form in the Northern Atlantic Ocean. As solar radiation warms the ocean surface evaporation increases. The warmer the temperatures, the greater the rate of evaporation. As you may recall, warm, moist air rises, expands and cools to the dew point and clouds form. Energy and water vapor continue to be added to the atmosphere. This creates a low pressure area, known as a tropical depression. If winds are sustained above 39 miles per hour it is considered a tropical storm. If the winds are over 74 miles per hour it becomes a hurricane. Most hurricanes occur in late summer early autumn because this is when the ocean surface is warmest. They are the most destructive storms. High winds, storm surges (ocean water pushed onto the coast) and major flooding occur. One more thing that adds to the hurricane Category Winds 1 74-95 mph 2 96-110 mph 3 111-130 mph 4 131-155 mph 5 > 155 mph disaster is that tornados can form. A hurricane is sometimes referred to as a cyclone because it is such a large area of low pressure. A typhoon is the same as a hurricane, however forms over the Northwest Pacific Ocean. Hurricanes are fairly easy to predict because advancements in weather radar and satellite technology allows meteorologists to watch them develop and keep track of their path. Where exactly they hit land is not full proof. If a hurricane appears to pose a threat to your area within 48 hours, a hurricane watch is issued. A warning is issued if conditions are expected within 36 hours. When you are ordered to evacuate LEAVE THE AREA. Need to know: 1. Where do hurricanes form? 2. How do clouds form in a hurricane? 3. What is added to the atmosphere to fuel the development of a hurricane? 4. What is a tropical depression? 5. What is the difference between a tropical storm and a hurricane? 6. What is the difference between a sustained wind and a wind gust? 7. How fast are sustained winds in a category 5 hurricane?

How has the frequency of extreme rainfall changed over the 20th century?Question 7Select one:a.It is likely that there has been an increase in the number of heavy precipitation events at the global scaleb.It is likely that there has been a decrease in the number of heavy precipitation events at the global scalec.It is likely that there have been increases in the number of heavy precipitation events in more regions than there have been decreasesd.There is low confidence that there are any robust long-term changes in the number of heavy precipitation events

Which is smallest tropical cyclones worldwide ?

An increase in river flooding in the United States over the last two decades has been attributed to rising ocean temperatures by some scientists. These scientists hypothesize that increasing ocean temperatures leads to an increase in the amount of water that is evaporated into the air. This evaporated moisture eventually condenses into droplets of water, which are released during rainstorms. Most river flooding in the continental United States is caused by periods of heavy precipitation, or rainfall. Which finding, if true, would most directly support the researchers’ hypothesis?There is a correlative relationship between the number of rainstorms reported across the United States and ocean temperatures: when one increases so does the other.eliminateSince the year 2000, average ocean temperatures have increased by around 1.2° Fahrenheit.eliminateMost rivers won't flood unless there is sustained, heavy rainfall for lengths of time longer than two hours, or less heavy rainfall for lengths of time longer than five hours.eliminateThe causes of river flooding not connected to periods of heavy precipitation, for example, larger snow melts than expected, have also been on the rise in the past two decades.
