The WeatherSTEM station at the University of Florida in Gainesville recently released a time lapse of every sunrise over the course of one year. You may pay the most attention to the different clouds in the sky, but we focused more on the position of the sun.

 

This time lapse does an excellent job showcasing how the sun’s angle changes as the year progresses. Seasons occur on Earth because of its 23.5 degree tilt, as we orbit around the sun the axis of Earth changes. Even though our planet is the furthest away from the sun during the summer, here in the Northern Hemisphere it’s the tilt that allows for the warmer weather — not the distance from the sun — especially in higher latitudes. This is due to the higher sun angle we see from the ground where the sun is almost directly overhead. While the Northern Hemisphere experience summer and a higher sun angle or higher position of the sun in the sky, the Southern Hemisphere is in winter, featuring a lower sun angle. During the middle of the  winter season in the Article Circles of both hemispheres, there can be several months of complete darkness depending on latitude.
