I live in Dhaka which is a tropical city in South East of Asia. This city is subjected to both kinds of UHI. While the canopy layer heat island is a very common phenomenon in commercial centers in Dhaka,The area I live in is is mainly victim of surface heat island. A high aspect ratio refers to narrow streets surrounded by high buildings- would be an ideal condition to express the condition of my locality. It should lead to low temperature, but increased surface areas and extended period of heat in summer causes surfaces to absorb and reflect much heat. I live in 13th floor of a 15 story building and often feel that low wind velocity is causing heat increase. Many apartments use artificial air conditioning system. This leads to some more heat reflection by surfaces. The heat island effect is very significant in the case of Dhaka. For example: for 5th August 2020, Recorded Temperature of Dhaka was 34 Degree C- 29.5 Degree C (Dhaka-Tejgaon Military Base, adjacent to first picture) For Gazipur (The area of 2nd picture)- The temperature is 32-27 Degree C (Gazipur District) So, far no measures are taken here to reduce this.
