Temperature Controls in the city of Dhaka in Bangladesh

     The capitol city of Bangladesh is Dhaka. The latitude and longitude of Dhaka is 23.7° N, 90.3750° E. The warmest month of the year in Dhaka id May, with a mean temperature of 29°C (84.2°F), and the coldest month of the year in Dhaka is December, with a mean temperature of 20°C (68°F). The annual range of temperature in Bangladesh is 9°C (48.2°F). This information was found at:

     A temperature control that has an impact on the city of Dhaka is ocean currents. Warm water is being blown by the wind up towards the poles. The wind then travels from the ocean, in this case the Indian Ocean, northward up from the coast of Bangladesh, and towards Dhaka. This contributes to the low range of temperature in Dhaka.

     Altitude is not a temperature control in Dhaka, or for most of Bangladesh, because the altitude for the whole country remains relative the same, and close to sea level. See map below:

It is predicted that within the next fifteen years the annual average temperature will go up about 4°C. While this may not seem like much, that small change could actually cause many problems for the city of Dhaka, and the country of Bangladesh. A ride in the average temperature causes sea levels to rise. If the sea level were to rise a few feet, the city of Dhaka, which is already a common flood zone, would suffer from more flooding. This could also possibly cause even more hurricanes with the warming water. Bangladesh already suffers from many natural disasters (flooding, hurricanes, tornadoes), and it seems will endure even more in the future.
