Global and Local Winds in Bangladesh

          There are multiple ways the location of Bangladesh affects the winds it receives.  Bangladesh is located 24°N and 90°E in the northern hemisphere.  This is located within the Hadley Cell in the three-cell atmospheric model, near the top by the horse latitudes where trade winds originate.  One of the global winds impacting Bangladesh is the north-easterly trade winds, which are coming from the north-east and blowing towards the south-west.  Bangladesh is also impacted by the subtropical jet stream located at 25°N, which tends to be weaker in the summer.  The location of Bangladesh is also near the subtropical high pressure belt.  So there are multiple global winds that have an effect on Bangladesh.
          The country of Bangladesh’s location plays a major role in determining what the weather and climate will be like.  In general, I think Bangladesh would have a fairly windy climate, considering there are so many types of global and local winds affecting the country.  One of the major winds that would affect the climate is the trade winds, which are consistently blowing south-west (see Global Wind Map below).

Also, because it is located between the subtropical high pressure belt, and the equatorial low, there should be a windy climate where the winds are travelling north to south.  This also, causes the air to converge at the subtropical pressure belt (horse latitudes), decrease in altitude, and then diverge out. (see Pressure Patterns Map below).

However, the subtropical jet stream could affect the weather conditions. This jet stream tends to be weaker in the summer, roughly around the El Nino season where the trade winds weaken as well. Sense the cause the north to south winds to weaken, the sea breeze is given an opportunity to bring moist clouds over the country of Bangladesh, and cause a lot of rain. This change in wind patterns in Bangladesh is referred to as a monsoon season.  The monsoon season is what prevents the country from having a dessert climate like many other countries around it, which have dessert climates due to being near the subtropical high pressure belt and the Coriolis Effect.  
          There are also some local winds that can affect Bangladesh.  There are no mountains in the country of Bangladesh.  Of the five winds and breezes that are associated with mountains -which includes mountain breeze, valley breeze, Chinook Winds, Katabatic Winds, and Foehn Winds- none of them have an effect on the weather in Bangladesh.  This is because Bangladesh is not located in the mountains or in a valley.  Local winds associated with coastlines have an impact on Bangladesh.  Bangladesh is located on the coastline of the Bay of Bengal in the Indian Ocean.  The 2 breezes associated with coastlines are sea breeze and land breeze, and both have an impact on Bangladesh.
