Summer heat anomalies in the northern hemisphere will become more persistent in the midlatitudes, especially in southern North America where summer weather patterns and associated temperature anomalies are projected to slow-down by more than 45% by the end of the century There are robust relationships...
While the temperatures may already feel like summer, the official start of the season began on Tuesday in the Northern Hemisphere — an event known as the summer solstice. During the June solstice, the sun travels along its northernmost path in the sky ...
The summer solstice occurs when the tilt of a planet’s semi-axis, in either the northern or the southern hemisphere, is most inclined toward the star (sun) that it orbits. Earth’s maximum axial tilt toward the sun is 23° 26′. This happens twice each year, at which times the sun ...
Viewers should also avoid strong moonlight, which happens only about 10 days per month, in order to easily view the Milky Way post dark during the summer months. According toCapture the Atlas, one can get a glimpse of the Milky Way from the Northern Hemisphere between March a...

The World Meteorological Organization (WMO) says Earth just had its hottest summer ever in the Northern Hemisphere. 世界气象组织表示,地球北半球刚刚经历了有史以来最热的夏天。 Summer ends on September 22 this year in the world's northern half. 今年,北半球的夏季将于9月22日结束。 Last month was...
While the exact definition of a season's timing and length can differ in different areas based on local conditions, in most of the Northern Hemisphere meteorological summer is generally defined as the three months of June, July and August, with the season starting on June 1 and ending on ...
