The circulation of oceans is very much like the atmosphere, which is freer and faster. There is greater total flow of ocean water towards the equator than towards the poles. The reason for this seems to be the excess of evaporation over precipitation in the doldrum* belt of greatest heat. The resulting rains stir the sea. The wind influences the water below it creating little ripples that are far more efficient than the bigger waves in absorbing energy from the sky. These ripples can be compared to atoms making up in coordination and numbers what power they lack as individuals.

In any mass movements people are like atoms whose ability to reason or give shape or direct is restricted. Instead their brute force is freer.

*Due to intense solar heating near the equator, the warm, moist air is forced up into the atmosphere like a hot air balloon. As the air rises, it cools, causing persistent bands of showers and storms around the Earth’s midsection.

Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. Here, the prevailing trade winds of the northern hemisphere blow to the southwest and collide with the southern hemisphere’s driving northeast trade winds.

Due to intense solar heating near the equator, the warm, moist air is forced up into the atmosphere like a hot air balloon. As the air rises, it cools, causing persistent bands of showers and storms around the Earth’s midsection. The rising air mass finally subsides in what is known as the horse latitudes, where the air moves downward toward Earth’s surface.

Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that’s why they call it the doldrums.(Source: ocean service. noaa.gov)
