He Winter Solstice in Argentinaand throughout the southern hemisphere, marks the start of the season coldest of the year The official season of hats, scarves and jackets begins this Wednesday June 21 at 11:58, being the shortest day of the year. In addition, they eagerly await the Winter Break What are they two weeks without classes beginning in July.
The solstices are linked to the tilt of Earth’s axis of rotation and its distance from the Sun. Winter begins in the southern hemisphere when “the south pole is further from the sun than at any other time of the year,” NASA explains.
In parallel, the north pole is closest to the sun, so the other half of the world celebrates the summer solsticeaccompanied by the arrival of the hottest months.
When does the winter solstice start?
This year, the winter solstice in the southern zone will be the Wednesday June 21 at 11:58 noon, according to the Naval Hydrography Service. The date of the solstice may vary slightly, but It is always between the 20th and 22nd of this month.
So, June 21 will be “the shortest day of the year” or “the longest night”, since the sun will reach the lowest point of the whole year. From there each time there will be more daylight until December 21, “the longest day of the year”. The exact opposite happens at the north pole.
He Earth’s distance from the sun not only determines that there are fewer hours of sunlightbut also a drop in temperatures. The coldest months of the year in Argentina are June, July and August.
Solstice and equinox: how are they different?
The solstices and equinoxes are astronomical phenomena that occur twice a year. The solstices mark the beginning of summer and winter, while the equinoxes mark the arrival of spring and autumn..
The The difference between one and the other has to do with the distance between the Sun and the axis of rotation of the Earth.. The Earth’s orbit is not circular, but ellipticaland that’s why it has a major axis and a minor axis: twice a year the Earth passes through the extremes of the major axis, and another two times through those of the minor axis.
When the Earth’s orbit coincides with one of the ends of the major axis, on the north and south poles, the solstices occur. The summer solstice (in the southern hemisphere around December 21) is the day with the shortest night of the year, and the winter solstice (June 21) has the longest night of the year.
Y when the sun is positioned exactly on the equator line (Earth’s minor axis), the equinoxes occur. They mark the early fall (March 21) and spring (September 21)and in those days the day and the night have the same duration.
