Why do we have seasons and how do they affect my life? We have seasons because the earth is tilted on its axis‚ as it makes its yearly journey around the sun. The Earth’s axis is tilted at an angle of 23.5 degrees. This means that the earth is always ‘pointing’ to one side as it goes around the sun. So‚ sometimes the sun is in the direction that the earth is pointing‚ but not at other times. The varying amount of sunlight around the earth‚ during the year‚ creates the seasons. We have hot

Celestial Sphere Terminology 1 Celestial Sphere:What we see‚ it contains the stars‚ planets‚ Sun‚ and Moon Celestial Equator- the imaginary line that divides the planet into Northern and Southern hemispheres. The celestial equator is a similar imaginary circle around the celestial sphere‚ also known as the visible universe. The celestial equator divides the visible universe in two‚ creating the Northern and Southern celestial hemispheres. This helps us locate celestial bodies. Ecliptics -an imaginary

Advanced Atmospheric Circulation Homework: Q1) Pressure areas around the equator constantly move North and South with the Seasons as they are affected by the Inter-Tropical Convergence Zone‚ which is the area encircling the earth near the equator where the northeast and southeast trade winds come together. Solar heating in this region forces air to rise through convection that results in plenty of precipitation. In addition‚ as the air rises due to convection in such regions‚ the pressure of that

The region of Earth receiving the Sun’s direct rays is the equator. Here‚ air is heated and rises‚ leaving low pressure areas behind. Moving to about thirty degrees north and south of the equator‚ the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator‚ most of the cooling sinking air moves back to the equator. The rest of the air flows toward the poles. The air movements toward the equator are called trade winds- warm‚ steady breezes that blow almost

latitude. The tropical zone is the closest to the equator‚ classified as being hot and humid with a small breeze. Meaning that even though there is a luminous sun‚ wind is also present. It extends from the equator to approximately Mexico on the northern range and Brazil to its southern range. Countries in between this range will have a tropical climate‚ but will also vary on their location. A country such as Ecuador‚ which is really close to the equator‚ is hotter‚ whereas a country farther‚ has lower

radiation striking the ocean near the equator warms the surface water and causes evaporation. Half of the incoming solar energy is utilized in converting water from the dense liquid to the lighter gaseous state. As the water vapor rises into the atmosphere and away from the equator it cools‚ condenses and falls as rain or dew. With the lightweight gaseous water vapor removed the dry air is heavy and denser and begins to sink. The area of lighter air rising near the equator creates a low pressure zone‚ whereas

Once the HSA is calculated‚ the VSA is given by: Shading Depth for Equator-Facing Surfaces An equator-facing surface is one that faces due South in the Northern hemisphere and due North in the Southern hemisphere. Surfaces at other orientations are substantially more complex and are dealt with in the section following below. However‚ for equator-facing surfaces‚ it is the VSA that determines the depth of any required shade. In order to shade to the very
