Severe Weather in Tanzania

      In this blog I will be talking about the severe weather that takes place in Tanzania. For starters I'll talk about Tornadoes. The formation of thunderstorms form due to a supercell thunder storm. In order for a supercell thunderstorm to form in needs to be in the presence of unstable air, forced to rise by the topography of the land, fronts, and Vertical wind sheer for the formation of the vortex tubes to form the rotating mesocyclone. In the United States tornadoes are move towards the northeast. This is the dominant direction because of the southerly winds as well as the mid-latitude westerlies.

The closest thing I could find similar to a Tornado is a Sand Tornado and a video on Vimeo of a baby tornado. Other than that I can't find any information stating that Tornadoes do not occur in Tanzania.

The Average number of Tornadoes recorded in the US pe
r year is over 1,000 per year

   Based on this map it can be seen that Tornadoes are not common in Africa especially where Tanzania is located. Tanzania lies to North of the Hotspot zone on Africa. The increase of Tornadoes over the past 30 years could be due to various reasons. Change in land topography and or global warming could be two possibilities.
   
     Three main requirements for a tornado to form is Warm ocean Temp of 80 degrees Fahrenheit, Deep warm ocean layer that is 200m in depth, and Coriolis between 5 degrees N, S. Based on these requirements Tanzania does not meet these requirements. However if a Hurricane were to hit Tanzania it would be the south eastern part of it. In the Atlantic and East Pacific Hurricanes don't have a different name like other regions do. In the Indian ocean Near Australia are called Cyclones. Off the coast of China and Indonesia Hurricanes are called Typhoons.

  In the United States the general path that a hurricane follows a path towards the Northwest form Southeast due to the trade winds. This is the dominant path because the trade winds from the east  move it to the North and West. Hurricanes do not occur in Tanzania. Average Hurricanes in Tanzania are Zero. The Average Hurricanes in the US are 6.2 hurricanes per year  

Daily Weather in Tanzania

    In this blog post I will be covering information about the daily weather in Dodoma. The capital city of my country Tanzania is Dodoma. The first this I will be covering is the 3 day forecast of my capital city. The three days I'll be covering are Wednesday, Thursday, and Friday. On Wednesday the forecasted  high is 91 degrees Fahrenheit and the forecasted low is 64 degrees Fahrenheit with a 0 percent chance of any precipitation On Thursday we see no change in the forecasted low and high which still remain at 91 and 64 degrees Fahrenheit also with the same 0 percent chance of precipitation. The same goes for Friday in my 3 day weather forecast, the same Forecasted high and low of 91 degrees and 64 degrees Fahrenheit and 0 percent chance of precipitation. Over a 3 day period the average pressure for Dodoma is 29.96. During this three day period the pressure stayed the same. Over the 3 day period the average wind speeds are 11.3 mph E. During this three day period the wind speeds stayed the same.

Based on the map above we can see that there are no clouds visible over Dodoma. We can see however that around Tanzania there are cold clouds to the North and South West. Based on the day I started this blog post there are no signs of Precipitation over Dodoma or the rest of Tanzania. When zooming in  on the map of Tanzania the closest body of water near Dodoma is lake Hombolo. Upon further examination there are signs of light vegetation in the city. Other than that there isn't much to look at in the city of Dodoma.

Based on the zoomed in map of Eastern Africa We can see there are two 1012 mb and 1016 mb isobars. Based the map above we can see that there are no signs of a significant low or high pressures. Also based on this map there are no signs of any type of fronts.

The isobar pressures that are observed are 1008 mb, 1012 mb, 1016 mb, 1020 mb and 1024 mb. There are two high pressures observed in this map to the south east and south west off of the coast of southern Africa. There is also one Low pressure on the north west corner of Africa. There are two types of fronts located on this map or three if you can make out the one behind the "Current Surface" label. The first type of front is the stationary front that can be found to the south east and south of Africa. The next type of front is a cold front on the north west corner of Africa.
