Why does London get so hot?
Another heat wave is expected to rise to weekend temperatures in the south of England to 30C degrees on Sunday.
Later on Monday, the Met Office estimated that temperatures can reach 34C degrees in London.
Met Office Spokesman Graham Madge said: “Temperature models are gradually rising and we believe that temperatures will be the hottest on Monday during this heat wave.”
“It is probably an isolated temperature in the South East, London, or maybe a place in Cambridge”.
This may mean that the country could see the hottest June day in which the previous record was 35.6C, both on June 28, 1976 at Southampton Mayflower Park and on June 29, 1957, Camden Square was recorded in Camden Square.
So, why is it so warming up in the capital? And is there a reason why London Heat feels much more unbearable?
Air Conditioning Lack
Unlike other countries that have temperatures above 30 ° C in the world, most of the houses in the UK are not lucky enough to have air conditioning to escape heat.
Although there are air-conditioned shops and offices in London, all public transport transportation is not luxurious-some results in a very sticky work.
However, although the air conditioner offers some relief in the city center stores, waste heat and vehicles from air conditioners can add temperature to the environment and increasing temperatures.
Buildings are designed for cold weather
For most of the year, the weather in the UK cooks a harder climate, not sunlight, as a result, the houses are designed to keep heat inside.
The country focuses on making insulated houses to reduce the use of energy and maintain heat in winter, but it means it can heat up this summer.
Dr. Oscar Broousse, an urban meteorology specialist at the University College London, Independent: “The buildings absorb heat efficiently because of the radiation and thermal properties caused by the common materials we use to build them.”
“These features can be changed by applying green or cool roofs, for example.”
Intensification of people in urban areas
The urban Heat Island effect is another phenomenon that emerged with an intense population.
“Living in a city can increase fragility to heat. Many deaths occur during heat waves due to the combined effect of high temperatures and urban micro climate,” he said.
Estimated, explained that the buildings were absorbed instead of reflecting the heat of the sun.
Dr Broousse added: “The buildings really release heat efficiently and can cool quickly.
“The problem in urban environments is that this heat is then backward to the surrounding buildings, so it delayed the cooling process, and especially in the early morning, it leads to the ‘urban heat island effect’, which is prominent just before the sunrise.”
In cities like London, high buildings and narrow streets reduce wind speeds and remove the trees and reduce the natural cooling effect of shading and evaporation.
Air pollution
Car smoke and the pollution of the aircraft caused by the top not only reduce air quality, but also increase heat by capturing.
“Air pollution may cause the effect of a layer of micro greenhouse gas and stop the spread of heat back to the atmosphere, M said Met Office.
Dr Brousse said: “Some aerosols can really affect incoming solar radiation and reflect the back of the incoming energy, so that it can have a protective effect.
“It can also contribute to the increase in cloud scope, which has significant effects on the heating/cooling of the land during the day/night.”
London’s location
Record -breaking temperatures are generally recorded in London and Kent, the southern and eastern parts of the British Islands.
Dr Brousse announced that heat waves tend to come from the southern and eastern continental climates.
He said: “As they move to the north, they lose energy, so that Southerner speaks relatively.
“All this contributes to average temperatures in the southeast of England. Beyond that, London observes a prominent urban heat island that further increases the average temperatures in the city.”
