Events occur by the position of the sun: Friday 21 this and part of Saturday 22 the output of the sun and sunset will last 14 hours and 13 minutes, averaging 60 seconds more than usual days. This can have an impact on weather phenomena such as storms, said an expert.

Some complain that those days are too long, maybe because of "irresistible" and the busy days of the last 2018; others, because that day is not enough. Well, this Friday, December 21 and part of Saturday 22, of 19.23 no Santa Fe will escape the astronomical event: called Summer Solstice (or December), the longest day of the year. It will last 14 hours and 13 minutes for the Santa Fe latitude, an average of one minute more than the other day.
The word solstice comes from Latin and means "the sun stops". In the province of San Juan, for example, people performed rituals of idolatry and Christians also held colorful parties. Some drink lots of water (as a symbol of purification); others, frantically cleaning the whole house, to clean it from "bad vibrations". And others throw away all clothes that bring back bad memories.
Outside of ritualism – a separate sociological phenomenon – there is an astronomical explanation: "Because of the tendency of the Earth's axis with respect to the sun (tends to 23.5 degrees), the southern hemisphere receives more direct sunlight, and the leanest is received in the north. on Fridays and Saturdays, the sun slows down, therefore it's called 'quieto sol & # 39;', explained Prof. Jorge Coghlan, director of the Code, told El Litoral.
"From now on, we will feel warmer, because the ocean is gradually warming up," he added. Like us Santa Fe here with very high heat, in Europe it's very cold. December 21 this is an intermediate date: mark (from astronomy) part of spring to summer. Same as all June 21 (transition from autumn to winter).
Solstice will last one and a half or two days. "Your departure and sunset at the same time, but with the difference that now the period of sunlight will last 14 hours and 13 minutes: it will be one more minute of sunlight. All of this is caused by how sunlight affects the northern hemisphere. it will be a little longer: this first knows, because they use the sun as a clock, "Coghlan said.
After this Friday and Saturday, in the transfer on the horizon, the sun will begin its journey north. From there the days will shorten the average duration of the minutes to Winter Solstice, which will occur on June 21, 2019.

Events in climate
Consulting at the solstice can affect climate, Coghlan added: "This is the time when seasonal changes occur, and weather events like this always occur, such as storms that are not on time. In a short time (in two weeks or a month) heavy rain, but this is also a cycle problem: if you look at the statistics for the last 50 years, this phenomenon has happened several times, "he added.
The climate is unstable, not exact or chronological science. "There are many variants that work with climate and are related to the dynamics of the atmosphere and the seasonal situation as well. For all of these human impacts are added: the percentage of human events since the beginning of the industrial age, more than three centuries ago, inevitably affected the climate," the director concluded.
