Why are cities hotter than rural areas?

Multiple parts of Country reeling under heat wave conditions. Cities, in particular, are hotter than rural areas. This is due to a phenomenon called ‘Urban heat Island”.

on Sunday, for For example, two zones in Delhi recorded temperatures Close to 50°C. Mongshpur recorded a temperature of 49.2 degrees Celsius, while it was 49.1 degrees in Najafgarh. The maximum temperature in Meanwhile, Gurgaon’s temperature rose to 48.1°C in Noida, it was 47.1 degrees. However, the temperatures around these cities were not that high.

So, what are urban areas heat Carrots, and why are they caused? Are there ways to mitigate it? Indian Express Explain:

What is urban heat Island?

urban heat An island is a local and temporary phenomenon that occurs when there are certain pockets within city experience higher heat Payload from surrounding or adjacent areas on same day.

For example, a greener area like Bashan in Pune often records cooler temperatures than urban areas like Shivajinagar, Chinchwad or Magarpatta.

The differences are mainly because of heat Stay trapped inside locations which often resembles a concrete bush.

The temperature can be changed range Between 3 to 5 degrees Celsius.

Why are cities hotter than rural areas?

Rural areas have a relatively larger green cover in the form of Farms, farmland, forests, and trees compared to urban spaces. This green cover plays a major role role in Organize heat in its surroundings.

transpiration is natural way of heat Regulation. This is the scientific process of Roots absorb water from the soil and store it in Leaves and stems of Plants before processing and releasing in the form of Water vapor.

On the contrary, urban areas lack sufficient green cover or parks and often do so developed with High-rise buildings, roads, parking spaces, sidewalks, transit roads for public Transportation. as a result heat Organizing is either completely absent or man-made.

physics us who – which black Or any dark colored object that absorbs all wavelengths of light It turns them into heat while reflecting them white.

Buildings are usually erected in cities with Glass, bricks, cement, concrete – everything of It is dark in color materialswhich means they attract and suck higher heat content.

Thus, temporary islands are formed within the cities where heat remains Trapped. These are not the typical islands around bodies of water, but they are urban heat the islands that record higher Daytime temperatures are more than other areas.

where were they heat Experienced carrots lately?

On May 15, Najafgarh and Mongshpur localities in Delhi registered maximum Temperatures of 49.2 ° C, while other locations in The city lower temperatures were recorded, like Mayur Vihar (45.4 °C), Lodhi Road (45.8 °C), Palam (46.1 °C), Ayanagar (46.8 °C) and Delhi Ridge (47.2 °C).

Experts say these temperature differences are caused by differences in heating over Highly urbanized and semi-urban areas have relative availability of Open and green spaces in Ocean. Besides, urban meteorological operations operate quite differently from state-side or semiUrban/rural areas.

How can urban heat be carrots reduced?

The main way To cut heat Intra-urban load increases green cover; Filling open spaces with trees and plants.

other ways of heat Dilution includes appropriate selection of Construction materials,promotion of garden and kitchen balconies,painting in white or light Colors on Terraced anywhere possible to reflect heat.

What did NASA say? on civilized heat carrots in India?

NASA recently indicated out heat carrots in urban parts of Delhi, where the temperatures were far higher of neighboring agricultural land.

NASA’s Ecostress Experiment captured a picture just before midnight of May 5, covering a area of About 12,350 square kilometers, which is shown in big red patch About Delhi and Red Smaller patches About nearby cities of Sonepat, Panipat, Jind and Biwani. This is red patchesWhich means higher Temperatures, were heat Rural areas around the cities experience lower temperatures.

“Night temperatures in Delhi and many small villages were above 95 degrees Fahrenheit (35 degrees Celsius), with a peak of about 102 degrees Fahrenheit (39 degrees Celsius), while nearby rural fields had cooled to about 60 degrees Fahrenheit (15 degrees Celsius), NASA said. in Declaration.

Ecostress is a tool with A radiometer sent to the International Space Station in 2018. It can measure temperatures on Earth, unlike air temperature. Earth temperatures are likely to be higher during the day from air Temperatures are almost the same during the night. In the first place, Ecostress . is commissioned with temperature measurement of Plants and understand their water requirements And the effect of the climate on With them.
