DIURNAL ARC Meaning and
Definition
-
Diurnal arc refers to the apparent daily path followed by the Sun in the sky as observed from a particular location on Earth. It describes the trajectory traced by the Sun from sunrise to sunset as it appears to move in relation to an observer. The diurnal arc is influenced by the rotation of the Earth on its axis and the tilt of the Earth's axis relative to its orbit around the Sun.
The path of the diurnal arc varies depending on the latitude and time of year. At the equator, the Sun appears to travel in a relatively straight line across the sky, resulting in a shorter diurnal arc. Conversely, at higher latitudes, the diurnal arc appears more elongated, with the Sun rising and setting at lower angles.
Throughout the year, the length of the diurnal arc also changes. During the summer solstice, the Sun takes a longer path across the sky, resulting in a higher diurnal arc and longer daylight hours. Conversely, during the winter solstice, the Sun has a shorter and lower diurnal arc, leading to shorter daylight hours.
The diurnal arc is a significant concept in various fields, including astronomy, geography, and navigation. It plays a crucial role in determining sunrise and sunset times, as well as the length of daylight hours at a specific location. Understanding the diurnal arc helps in predicting seasonal variations, optimizing solar energy collection, and studying the Earth's rotation and tilt effects on climate and weather patterns.
