Seasons and Why the Equator is Warmer than the Poles A closely related and perhaps more common misconception is that the equator is warmer than the poles because the equator is significantly closer to the sun than are the poles (i.e. the equator bulges out toward the sun). Even professional geoscientists sometimes hold the latter misconception.

- So, sometimes the Sun is in the direction that the Earth is pointing, but not at other times. The varying amounts of sunlight around the Earth during the year, creates the seasons. The tilt of the Earth's AXIS is the most important reason why seasons occur.We have hot summers and cold winters because of the tilt of the Earth's axis. The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later.id you know? The Earth's movement around the sun causes the seasons, but it does not affect the temperatures during the seasons. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter.

- The tilt of the Earth means that when sunlight does reach the poles, it is diffused, or broken up, by the planet's atmosphere. This reduces the heating effect of sunlight. A similar but less drastic effect causes cold winters in the temperate areas between the poles and the Equator.

- The solar heating is uneven due to the variations of the surface. Heat flows from high to lower temperatures. This fact, and the cycles of day and night, and changes in surface heating due to the seasons cause wind currents to circulate around the world. These persistent winds drive surface ocean currents. One of these important currents is flowing off the coast of Florida.

Mercury's magnetic field At the Hermean equator, the relative strength of the magnetic field is around 300 nT. Although much weaker than Earth's magnetic field (about 1/100 its magnitude) according to Mariner 10 data, the magnetic field is still strong enough to deflect solar wind emissions, inducing a magnetosphere.

General Circulation of the Atmosphere The circulation cell closest to the equator is called the Hadley cell. Winds are light at the equator because of the weak horizontal pressure gradients located there. The warm surface conditions result in locally low pressure.The warm air rises at the equator producing clouds and causing instability in the atmosphere. This instability causes thunderstorms to develop and release large amounts of latent heat.he warm surface conditions result in locally low pressure.

The ocean plays a fundamental role in shaping the climate zones we see on land. Even areas hundreds of miles away from any coastline are still largely influenced by the global ocean system. Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off. The world’s ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun’s radiation is absorbed by the ocean. Particularly in the tropical waters around the equator, the ocean acts a as massive, heat-retaining solar panel.

- Report Abuse. America gets hit by summer when its getting all the sun from position of equator of the sun. This happens for Australia in the winter for us. Has nothing to do with pole rotation lol. The earth spins like a top so thats why some summers are more hot than others and vice versa for winter. The sun lets out certain amounts of Gamma radiation and spikes with sun flares which gives life to our planet.

Why Is it Hot at the Equator But Cold at the Poles? atlas globe image by Jorge Casais from Fotolia.com. The tilt of the Earth's axis causes the difference in temperature between the Equator and Earth's polar regions. While the Equator receives direct light from the sun at all times of the year, the tilted axis prevents the poles from receiving such prolonged exposure.

- The South Equatorial Currents of the Atlantic and Pacific straddle the equator. Though the Coriolis effect is weak near the equator (and absent at the equator), water moving in the currents on either side of the equator is deflected slightly poleward and replaced by deeper water.

Why are tropical rainforests near the Equator? A tropical rainforest is typically hot year round with little temperature change from month to month. Tropical rainforests are near the equator because the climate there is warm, very wet and constant due to the position of the sun over the equator; it's always directly overhead.The plants that live there thrive in these conditions. There are only two seasons in the tropical rainforests: wet season and dry season. tropical rainforest is typically hot year round with little temperature change from month to month. Tropical rainforests are near the equator because the climate there is warm, very wet and constant due to the position of the sun over the equator; it's always directly overhead.

- Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum. Extreme Ultraviolet Sun. All electromagnetic waves (EM) travel at a speed of approximately 3.0 x 10 8 m/s in vacuum. Although space is not a perfect vacuum, as it is really composed of low-density particles, EM waves, neutrinos, and magnetic fields, it can certainly be approximated as such.

- At the stratopause, the temperature stops increasing with altitude. The overlying mesosphere does not absorb solar radiation, so the temperature decreases with altitude. At the mesopause, the temperature begins to increase with altitude, and this trend continues in the thermosphere. Here solar radiation first hits the Earth’s atmosphere and

Beta Volantis Over the course of its 84-year orbit, the north pole of Uranus is facing towards the Sun, and the south pole is in total darkness. And then the situation reverses for the rest of the planet’s journey around the Sun. Instead of heating the clouds at the equator, the Sun heats up one pole, and then the other. You would expect the pole facing the Sun to warm up, and to have air currents move towards the other pole. But this isn’t what happens. The weather on Uranus follows an identical pattern to what we see on Jupiter and Saturn.

The Tilting of the Earth: Shaping Our Seasons and Climates The sun’s energy is more concentrated on the Northern Hemisphere where its rays hit the Earth more directly and are thus more intense. At the same time, however, the Southern Hemisphere tilts away from the sun, causing the sun’s rays to hit the region more at an angle and with less intensity.

Why are Seasonal CO2 Fluctuations Strongest at Northern Latitudes? In general, researchers found strong seasonal CO 2 fluctuations throughout the Northern Hemisphere and weaker fluctuations near the equator and in the Southern Hemisphere. The station at Barrow, Alaska (71° N latitude), for example, experiences enormous swings in seasonal CO 2.

Solar Energy The Australian continent has the highest solar radiation per square metre of any continent and consequently some of the best solar energy resource in the world. The regions with the highest solar radiation are the desert regions in the northwest and centre of the continent.owever, Australia's current use of solar energy is low with solar energy accounting for only about 0.1 per cent of Australia's total primary energy consumption. The most common use of solar energy is solar thermal water heating. Solar PV systems play an important role in off-grid electricity generation in remote areas.

Geography-What is Insolation Geography-What is Insolation. Insolation is nothing but solar energy received on the earth. The sun emits radiation continously in the form of short wave and ultraviolet radiation, this radiation has to pass the atmosphere before it reaches the earth.attitude affects the distribution of the Insolation, Lattitude affects by affecting the angle of the sun rays and length of the day. Insolation is higher in the areas getting vertical sun light while meager in the areas of slanting rays. Lengthier day gets more energy than shorter day.

Ocean Currents Areas near the equator receive more direct solar radiation than areas near the poles. However, these areas do not constantly get warmer and warmer, because the ocean currents and winds transport the heat from the lower latitudes near the equator to higher latitudes near the poles. Large quantities of heat can be absorbed and stored in the surface layers of the ocean. This heat is transported by ocean currents. In this way, the ocean currents help regulate Earth's climate by facilitating the transfer of heat from warm tropical areas to colder areas near the poles. The water of the ocean surface moves in a regular pattern called surface ocean currents. On this map, warm currents are shown in red and cold currents are shown in blue. Image Credit: Windows to the Universe. The global wind patterns cause the surface currents to form in the uppers layer of the ocean.

Hadley cell The major driving force of atmospheric circulation is solar heating, which on average is largest near the equator and smallest at the poles. The atmospheric circulation transports energy polewards, thus reducing the resulting equator-to-pole temperature gradient.he Hadley system provides an example of a thermally direct circulation. The thermodynamic efficiency of the Hadley system, considered as a heat engine, has been relatively constant over the 1979~2010 period, averaging 2.6%.
