Severe Weather in Tanzania

Tornadoes:

Tornadoes are formed by a rotating body of air from the ground, which is caused by vertical wind sheer. Then a horizontal rotating air is lifted by the thunderstorm's updraft. When the horizontal air mass is lifted almost vertically, it's a mesocyclone. In the U.S. the tornadoes usually travels from southwest to northeast direction. Tornadoes move in that direction because tornadoes move with the same direction as their thunderstorm. Thunderstorms usually move that way in the temperate parts of the northern hemisphere and because of the jet stream moving from west to east. Tornadoes don't usually occur in Tanzania while in 2011, the United States confirmed 1,625 with 93 tornadoes still pending for the month of November and December. Based on the graph below, it appears that tornadoes has increased in number over the past thirty years. This might not be true because it also depends on the technology. In the past 30 years they didn't have as much technology as we did or the data isn't as accurate as it is now.

Hurricanes:

The three main parts to form a hurricane includes warm ocean temperature of over 80 degrees Fahrenheit. The second part is a deep warm ocean layer in depth because the ocean water will mix and if the bottom layer is cold, when it mixes to the top, the ocean won't be warm enough to create a hurricane. The last part is coriolis to initiate the spinning of the hurricane. My country doesn't meet the needs to create a hurricane because the country is located in the southern part of the Atlantic Ocean where there is a strong wind shear present almost all the time. The main hurricane formation regions are

in the Atlantic and East Pacific called hurricanes, in the Indian Ocean by Australia called cyclones and by China and Indonesia called Typhoons. In the U.S. the general path hurricanes travel is like in a C shape along the east coast. This usually happens because the Hurricane forms over the warm Gulf stream and is steered by the west east flow of the westerlies and jet stream. The hurricane starts to die down when it reaches the cool north Atlantic Ocean. Hurricanes don't usually happen in my country because the location doesn't have a good enough wind shear. The average number of hurricanes that hit the US per year is six.
