Summer in the northern hemisphere has not yet officially arrived, but some countries and regions have experienced extreme high temperatures, and in recent days, many parts of India have experienced high temperatures of more than 37 ° C in many areas, such as Bangura, Prusia, Siberdwan, Hughley, Jagram and Mulhidabad.
Delhi, India, saw its highest temperature in April in 12 years
37 ° C high temperature is nothing, the Indian capital city of Delhi also directly appeared 43.5 ° C extreme heat, is India's 12 years of April temperature is the highest temperature, this is simply a heat wave rolling, if the hot summer officially arrived, really dare not imagine how high the temperature is.
On April 29, the Indian Meteorological Service (IMD) issued a high temperature orange alert to Delhi: the Delhi heat wave is expected to last until May 2, until the arrival of the western disturbance (ocean cyclone), Delhi is likely to be cloudy, and there may be rain, then the delhi heat will be alleviated.
The Indian Meteorological Service (IMD) predicts that in the next 5 days, many parts of India will usher in a "heat wave", Safdar Xinjiang may have a high temperature of 44 ° C, remote areas will have a serious heat wave, and even may appear in the evening or night gusts of 40-50 km / h, triggering sandstorms.
The Indian Meteorological Service (IMD) uses four color codes for each of the four high-temperature weather warnings, with "green" representing local no action required, "yellow" representing local wait-and-see and staying updated, "orange" representing that everyone is ready, and "red" representing local action.
Now, the orange warning of the high temperature in Delhi, India, has been issued, which means that the citizens of Delhi need to be prepared for heat protection and cooling, such as preparing electric fans, as well as the "water air conditioner" invented by the Indians themselves, if the conditions are good, they can also use air conditioning to cool down, but the local government will not take action.
Delhi, India, was indeed hot in April this year, with 8 "heat wave days" with high temperatures above 40°C recorded in April, 4.5 notches higher than normal in previous years, bearing in mind that in the past 22 years, April exceeded 40°C "heat wave days", only 6 were recorded in 2017 and 11 were recorded in 2010.
At this time of year, cyclical rainfall is typical of the climate environment in northwest India, but in late March this year, northwest India did not usher in periodic light rains and thunderstorms, and there was a lack of active western interference, which meteorological experts believe led to a rapid rise in temperature in northwest India.
Why are india's temperatures so high all year round?
There are two main influencing factors here, one is the factor of latitude location, and the other is the factor of geographical location.
Although the western part of the continent is closely adjacent to the eastern part of India, as far as the world map is concerned, the latitude of the continent is still a little northerly than that of India, which is tropical and subtropical between 8 ° and 34 ° north latitude, and the continent is in the temperate and subtropical zones of 20 ° -50 ° north latitude, which naturally determines that the annual temperature in India is definitely higher than the annual temperature of the mainland.
The geographical location also determines that india's annual temperature is warmer, the north of India is the Himalayas, the south is the Indian Ocean, the Himalayas are the highest mountain range in the world, blocking the "cold air mass" from the Arctic, so there are very few cold waves in India, and the mainland winter and spring will appear every year.
At the same time, India has become a "channel" for the ocean "hot air mass" to move in the direction of East Asia, which is naturally a subtropical climate, and the climate environment of the mainland Yunnan is affected by the marine "hot air mass" from the indian direction, forming a unique high branch trough climate environment, which is why India's perennial temperature is so high.
How do Indians with only 5% air conditioning live?
Use air conditioning when the weather is hot, which is the method used by most families in the mainland to prevent heat and cool down, but not every family in the world can afford to use air conditioning, according to statista research department in 2016 public data show that Japan is the world's highest proportion of households installing air conditioning, reaching 91%, and then the United States and South Korea.
The proportion of household air conditioning installation in the mainland reached 60% in 2016, in recent years, the mainland economy has developed rapidly, 6 years have passed, the proportion of household air conditioning installation should be more than 80%-90%, but India in 2016 home air conditioning installation ratio of only 5%, that is to say, 95% of the households do not have air conditioning.
It is no wonder that many Indian families have just solved the problem of food and clothing, where is the extra money to enjoy summer air conditioning? India's summers are so hot, often experiencing extreme heat, how do Indians with only 5% air conditioning live?
In fact, more than ten years ago, most of the families in the mainland did not have air conditioning, the days are not the same, hand fans, electric fans are used, even the nearby caves and "air raid shelters" can be opened to use, the cave inside the cool is very cool.
Indians also have traditional hand fans, but it is not the same as the traditional hand fans in the mainland, very personality, India also has electric fans, some electric fans do have national characteristics, a look to know that it is an Indian electric fan.
In addition, Indians have also made "water air conditioning" that belongs to Indian characteristics, many families have it, it is said that the effect is good, and the most important thing is that the price is cheap.
It is understood that the production principle of "water air conditioning" is somewhat similar to the "cold air machine" with cooling water, the water tank is filled with wheat rods, the wheat rod is used to breathe and absorb water, the water tank is used to supply water, and a fan is added inside, and the air circulation makes the water in the wheat straw gap quickly evaporate to reduce the local temperature, and the fan then blows out the low temperature airflow to achieve the effect of cooling.
Indians also have one of the best ways to cool down, that is, by playing with water to reduce the temperature, in the heat wave rolling days, the Indian Ganges Will gather a large number of men and women, the scene is lively and spectacular, Indians play in the river, play in the water, a joy and laughter.
In short, Indians also have a way of cooling down from the heat of Indians, let's imagine that in the era of no electricity, human beings did not spend the summer in their own way.
