The circle storms that are called tropical cyclones happen all over the worlds tropical oceans. One of the worst disasters in U.S. history was the Mississippi river flood of 1927,in which the Mississippi river overflowed its banks and following months of heavy ran. Floods are really catastrophic killing and injuring great numbers of people and destroying homes,farms,businesses,hospital schools and other properties. The Bahamas started to get a tropical depression after the storm in August 23 2005. Hurricanes are intense circular storms that originate over tropical oceans. Weather occurs within the atmosphere,the mixture of gasses that completely evelopes Earth.
The national hurricane center gave official names to storms they were all female names,that began in 1953 but then ended in 1978. 40 percent of the hurricanes that have occur in the United States hit Florida. Hurricanes are large spiraling tropical storms that can pack wind speeds over 160 MPH. They release more than 2.4 trillion gallons of rain a day. Rotating storm clouds create the eye wall , which is the most destructive part of the storm. Hurricanes rotate in a counter-clockwise direction around the eye.
The first ever hurricane happened in 1943 during WW||.90 percent of deaths that occur during hurricanes is because of floods created by this disaster. A huge hurricane can release energy equivalent to 10 atomic bombs per second. They can have a diameter of 600-800 kilometers. Hurricanes are first formed in warm moisture atmosphere by swirling above tropical ocean water. Hurricanes also produce milled tornadoes, which can last up to a few minuets.
Hurricanes are one of mother natures most dangerous and stunning storms. Only 5 category hurricanes have hit the United states since the beginning of the 20th century. Hurricane katrina is one of the most costlyest hurricane to hit the United States, causing some $125 billion worth of damage in new orleands and across much of the gulf coast. The smallest tropical cyclone on record is 1998`s tropical storm Marco with gale force winds extending out only 12 miles (19 killometers). 83 percent of category 4 or higher that have hit the United States have hit either Florida or Texas. The longest-traveling storms in the record traveled about 7,165 miles (13,280 killometers).
Usually hurricanes last up to 2 weeks. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from sea water increases their power. The center of the storm or the ´´eye`` is the calmest part of the storm. Hurricanes only form over really warm ocean water of 80 degrees or warmer. The crews release tools that measure tempratures,air pressure,and wind at different levels as the devises drop through the hurricane forwards the ocean
If the Earth did not spin hurricanes would not happen. Usually hurricanes are 300 miles wide. Every year at least 10 tropical storms hit the Atlantic Ocean,Carribiean sea,and golf of Mexico. The eye wall surrounding the eye is composed of dense clouds that contain the highest winds in the storm. Ocean waters must be above 26 degrees celsious to have a hurricane tropical force winds can stretch out as far as 300 miles from the center of a large hurricane.
The record for the strongest hurricane based on maximum sustained winds was set by hurricane Patricia when it rapidly intensified in the eastern pacific during the late October 2015. In the Atlantic basin the all time record is quite impressive as well at 27.75 days set by an unnamed storm in 1899. Two seprate Atlantic hurricanes dating back to 1944 have held category 5 status for a combined three days. Category 5 hurricanes have winds of 157 MPH or greater. In 1994 a storm stuck around for 30 days in the pacific ocean.
