In the United States and throughout the Northern Hemisphere, the final weeks of… Autumn astronomicThe ends December 21, 2025when the solstice marks the shortest day of the year and officially begins the boreal winter.
It will be the last day of autumn Saturday December 20th and winter will begin Sunday, December 21st with the solstice. So that’s it coldest season in the United States.
According to the time and date, the winter solstice will occur in 2025 December 21st at 9:03 a.m. (CST) or 10:03 a.m. Eastern Time.
In the USA, the climate crisis is already over. This measurement reports Met Office, It is used because seasons are defined as periods of time three full months (September-November for fall) it’s easier Compare temperature and precipitation statistics Year after year and work with climate models.
The meteorological (or climatic) autumn in the northern hemisphere runs from September 1st to November 30th.
He Winter solstice It’s that time of year when… One of the Earth’s poles is more tilted in the opposite direction to the sun, which creates the day fewer hours of light and the longest night of the year in the Northern Hemisphere.
Accordingly Time and date, happens because The Earth’s axis of rotation is tilted in relation to its orbit, and on this day the North Pole is further from the Sun and therefore receives less direct light.
This is how this astronomical event occurs Changes in weather conditions such as:
Although daylight hours increase at the end of autumn, Temperatures will continue to fall in most regions in winter.
This is because both the Earth and its oceans do not warm or cool immediately. They need time to adjust their temperature. This delay in thermal response is called the seasonal delay.
The seasons exist because the earth’s axis is tilted and It maintains this posture as the planet orbits the sun.
According to an educational report from the National Aeronautics and Space Administration (NASA), this tilt causes the globe One hemisphere receives more light and heat while the other receives less radiation.
When a hemisphere is tilted toward the Sun, spring and summer are recorded. On the contrary, when it is oriented in the opposite direction, autumn begins and then winter.
This process, repeated every year, creates variations climatic conditions typical of summer, autumn, winter and spring.
