![Surrounding][2] Two pictures show Colombo city which is the capital of Sri Lanka and its surrounding around few kilometers away. As you can clearly see city has tall buildings and narrow streets whereas surroundings area is having marshy lands. Tall buildings reflect radiation and increase temperature. In surrounding area, not much reflecting surfaces. Also, tall buildings prevent wind from sea entering into the city. However in nearby areas, not much barriers for the wind and better mixing of air is available. Increasing green spaces, design roofs of future buildings as green roofs can prevent some amount of UHI effect. Still enough attention is not directed to these issues.
