In this article we are going to talk about Effect of Sun angle on climate and its impact on modern society. Effect of Sun angle on climate is a topic of great relevance today and has generated constant debate in various spheres. Since its appearance, Effect of Sun angle on climate has sparked the interest of experts and fans alike, generating endless opinions and theories that seek to give it meaning and understanding. Over the years, Effect of Sun angle on climate has been the subject of studies, research and analysis that seek to decipher its true meaning and the implications it has on everyday life. In this article we will explore different perspectives on Effect of Sun angle on climate and its role in the contemporary world, analyzing its many facets and how it has shaped the reality in which we live.
The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the angle at which sunlight strikes Earth varies by location, time of day, and season due to Earth's orbit around the Sun and Earth's rotation around its tilted axis. Seasonal change in the angle of sunlight, caused by the tilt of Earth's axis, is the basic mechanism that results in warmer weather in summer than in winter. Change in day length is another factor.
Figure 1 presents a case when sunlight shines on Earth at a lower angle (Sun closer to the horizon), the energy of the sunlight is spread over a larger area, and is therefore weaker than if the Sun is higher overhead and the energy is concentrated on a smaller area.
Figure 2 depicts a sunbeam one mile (1.6 km) wide falling on the ground from directly overhead, and another hitting the ground at a 30° angle. Trigonometry tells us that the sine of a 30° angle is 1/2, whereas the sine of a 90° angle is 1. Therefore, the sunbeam hitting the ground at a 30° angle spreads the same amount of light over twice as much area (if we imagine the Sun shining from the south at noon, the north–south width doubles; the east–west width does not). Consequently, the amount of light falling on each square mile is only half as much.
Figure 3 shows the angle of sunlight striking Earth in the Northern and Southern Hemispheres when Earth's northern axis is tilted away from the Sun, when it is winter in the north and summer in the south.
Heat energy is not received from the Sun. Rather, radiant energy is received and this results in change in energy level of receiving bodies in Earth's domain. Different materials have different properties for transmitting back received energy in the form of heat energy at different rates.
