Most of the sun's energy is stored in the oceans because of the very large heat capacity of water compared to other earth's surfaces. The tropics and mid latitudes regions get more sunlight because they receive the radiation from the sun in a more direct way than higher latitudes (due to the sphericity of the earth and the sun being very far away from the earth).

Dr Alberto Marcelo Mestas Nunez thank you for your contribution to the discussion

The ocean covers the majority of Earth's surface and helps to store and transport heat in the climate system. Covering approximately 70% of Earth's surface, the ocean acts as a vast heat storage device in the climate system. Solar radiation is the fundamental energy driving our climate system, and nearly all climatic and biologic processes on Earth are dependent on solar input. Energy from the sun is essential for many processes on Earth including warming of the surface, evaporation, photosynthesis and atmospheric circulation.The energy per unit area is a maximum where the incoming radiation is closest to vertical (90 degrees) to the earth's surface. Equatorial regions average the most, with Polar Regions the least. The equator is where solar energy contacts earth at the most direct angle (90degrees). Most of the energy in the Earth's system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. The Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun. Consequently, as Earth orbits the Sun, the North Pole is tilted towards the Sun for about 6 months, and the South Pole is tilted towards the Sun for the rest of the year bringing the much needed sunlight to those regions. Because Earth is a sphere, not all part of the Earth receives the same amount of solar radiation. More solar radiation is received and absorbed near the equator than at the poles. Near the equator, the Sun's rays strike the Earth most directly, while at the poles the rays strike at a steep angle.Because of the Earth's tilt the sun's rays strike the surface at a slant at the poles; they are less focused. The tilt of the Earth causes different areas to receive different amounts of solar energy. The difference in solar energy received at different latitudes drives atmospheric circulation. This is because the Earth's imaginary axis isn't straight up and down, it is tilted 23.5 degrees. The Earth's movement around this axis causes the change between day and night. During summer in the Northern Hemisphere, daylight hours increase the farther north you go. The Arctic gets very little darkness at night. Covering approximately 70% of Earth's surface, the ocean acts as a vast heat storage device in the climate system. Ocean circulation serves to transport heat from the equator to the poles. In addition, gases from the atmosphere can dissolve in the ocean and be stored for many years in its depths. The Earth traps most of its energy at the land-ocean surface, so that the atmosphere is heated from below, and the oceans are warmed from above. Besides that, the surface heating is uneven. Much more heat is absorbed at low than at high latitudes. The earth is closest to the sun. The distance between the earth and the sun is about 93,000,000 miles or 150,000,000 km. Owing to the proximity of the sun and the earth, the earth get more energy from the sun than from all the other stars in the universe combined.
