The Earth is farthest from the Sun, but why is it so hot?

On July 6, the Earth was farthest away from the Sun. But why is the weather so hot?

The weather is hot, the temperature rises to record levels taking place in the past week in the world, in North American cities like Denver, Colorado; Burlington, Vermont; and Montreal, Quebec; as well as in European cities and Russia. But this is something that can be confusing for you: on July 6, the day when the Sun is farthest away from Earth. So what?

You all know about how seasons work. But maybe some people think that the hottest time of the year is when the Earth is closest to the Sun. So what?

The Earth and the Sun look from the ISS International Space Station.

According to Gizmodo, the Earth moves ellipse around the Sun. At the time of Earth's most distant Sun, particularly on July 6, the Earth would be 94.507803 miles away from the Sun (152,095,566km). To understand how far the Earth is from the Sun, it is possible to imagine an average of about 93 million miles (150 million km) away from the Sun, and on January 3, 2019, the Earth will be 91,403,554 miles from the Sun (147,099,761 km).

In fact, that is not a big difference in distance, if you consider the vastness of space. Meanwhile, the seasons are determined by the direct illumination of the sun's rays, and this is determined by the tilt of the Earth.

The Earth tilted at an angle of 23.5 degrees in orbit around the Sun. That means that in June and the months around June, the sun's rays are directed at the northern half of the Earth, and in January and the months around January, the Sun shines directly into the southern half of the Left. Land. In March and September, sunlight shines balanced on both hemispheres.

The more the sun shines directly, the more light reaches the Earth. Imagine when you hold a bunch of straws, in which each straw is a sun ray, and try to project them into the glass - like the surface of the Earth. If your glasses are straight with a straw, many lenses will shine straight into the glass. More straws, more rays; more rays, more energy; more energy, will be hotter.

The reason why the northern hemisphere is so particularly hot at this time is quite complicated. It is summer, so the weather will be hot, and sometimes even hotter than usual - that unusual heat is not just due to climate change statistics. According to an article in the Washington Post, there is a heat dome in the northern half of the earth - an area with high atmospheric pressure compressing the air, adding to the summer heat.

But climate change cannot be completely impervious in this summer's extraordinary heat. When things get warmer, we can see that the heat wave level increases so often. And according to the NOAA US Meteorological Agency, 2016 is the hottest year in history, 2015 is the second most intense year, 2017 is the third most hotly recorded year.

You won't be the only one who thinks the hottest time is when the Earth is closest to the Sun. So, share this article, knowledge of the hottest day is the day "the sun's rays shine directly on Earth" , that knowledge will make you . stand out.
