When Winter Begins: Essential Facts And Timeline
Winter's onset is a meteorological phenomenon triggered by Earth's axial tilt and its orbit around the sun. As the Northern Hemisphere tilts away from the sun, the days shorten, and nights lengthen, resulting in decreased solar radiation reaching the Earth's surface, which leads to colder temperatures. The winter solstice, the shortest day of the year, marks the official start of winter in the Northern Hemisphere.
