Web5 apr. 2024 · Low sun angles, such as those that occur during the winter months, can help support the health of forests. During these times, the lower angle of the sun's rays increases diffusion, which can allow more sunlight to penetrate through the canopy of trees, thus providing additional light and warmth for the lower layers of the forest. http://fsec.ucf.edu/en/publications/pdf/FSEC-DN-4-83.pdf

Websun angles change, depending on the season, the orientation, and time of the day. Generally speaking, summer sun angles are high (up to 75°) and winter angles are considerably lower (up to 29°). Furthermore, midday sun in the North is higher than morning or evening sun in the East and West. North: Due to the sun’s high angle in summer, WebA more direct sun angle in the northern hemisphere causes the warmth of summer, while simultaneously, a lower sun angle in the southern hemisphere brings less solar heating power and the chill of winter.
