According to www.weather.com during the autumnal equinox, day and night are balanced to about 12 hours each all over the world. Instead of the Earth tilting away from or toward the sun, its axis of rotation becomes perpendicular to the line connecting the centers of the Earth and the sun.
“This change in the tilt causes the change in seasons with the northern hemisphere moving from the warmth of summer to the chill of winter,” said weather.com digital meteorologist Linda Lam. “This process includes a shift in the overall location of the jet stream which plays an important role in weather conditions.”
From that point on, daylight in the Northern Hemisphere gradually becomes shorter up until the winter solstice. This is the opposite of what occurs in the Southern Hemisphere, where daylight won’t grow any longer.
Here in Kentucky the days will now start getting shorter and it's time to make those last fall planting and anything that may winter over.
