Astronomical summer is sometimes defined as the beginning of maximum solar radiation, often as the 21st day between June and December. The meteorological definition of summer also agrees with the commonly accepted notion that daylight prevails during the longest and warmest days of the year. If summer is summer in the northern hemisphere, it is usually winter, and the equinoxes and solstices would be the middle of their respective seasons.
In Australia, Austria, Denmark, Russia and Japan, the seasonal meteorological calculation is used by the International Meteorological Organization , the United Nations, the European Union and other international organizations.
The reason we have a solstice time is that the Earth does not orbit the Sun completely upright. The planet is tilted 23.5 degrees around its axis, meaning that one hemisphere receives more direct sunlight than the other at different times of the year. In summer, the northern hemisphere tilts toward the sun, giving us the most direct sun at the equator, and the southern hemisphere in the opposite direction.
Here, places in the southern hemisphere are thrown out of winter and in the northern hemisphere into summer, where they return to their normal summer temperatures.
The time of the June solstice is not due to a specific calendar date or time, but depends on when the sun reaches its northernmost point near the equator. The sun's rays hit the earth simultaneously with the sun's shadow, causing an efficient warming process known as summer. Note how high in the sky the sun appears during the solstice, and note that the probability of the shadow getting shorter this year is high. If you are in a city or city with sunlit skies or on a day when the solar system is high in the sky, you will find that there are fewer shadows than in the past, because the shadows will have been shorter this year due to the lack of sunlight.
If you live in the southern hemisphere, it is the shortest day of the year and marks the beginning of winter, but if you expect only hours of daylight, the summer solstice marks a midpoint, not the beginning of a season. Days lengthen from the equinox to the solstice, and summer days gradually shorten after the solstices. The meteorological summer covers the whole month of June, July, August, September, October, November, December, February, March, April, May, June and July .
Because summer conditions vary widely across Canada's vast territory, midsummer often takes place on July 1, though the dates close by vary traditionally. In the United States, similar Canadian traditions begin with summer on June 1 and end on Labor Day. The shortest night of the year is the summer solstice, the longest of the equinoxes.
That's why July is almost always the hottest month of the year in most places, says climatologist Brian Brettschneider, which is why meteorologists call it summer. But the real heat is yet to come, and summer feels like it is, according to the US National Oceanic and Atmospheric Administration . On average, July is about 1.5 degrees Celsius above average in the US and about 2.7 degrees in Canada.
These temperatures reflect the fact that the solstice marks the brightest and darkest day of the year, and it is also the time of year when the sun is at the highest point of the northern hemisphere.
This year's coldest temperatures set a record for the first time in more than 2,000 years, according to the National Oceanic and Atmospheric Administration. During this time, the earth's land and water need some time to heat up and cool down, and the thermometer reaches its lowest point of the year in the northern hemisphere, at about 4 degrees Celsius.
As a result, the summer solstice is not considered the first day of summer, according to the National Oceanic and Atmospheric Administration .
Astronomically, however, it is the first day of summer when the sun reaches its highest point in the sky, which occurs at the summer solstice . Therefore, the summer solstice is astronomically considered the "first day of summer." Since almanacs are defined as celestial calendars, I prefer to follow the astronomical interpretation of this season. I think it is good that the second - until - last week of June, 21 to 23 June, coincides with the summer solstices, because it marks the end of winter.
