Mesoscale convective systems which form in tandem with tropical waves that move along the Intertropical Convergence Zone during the summer months become the seedlings for tropical cyclones which form in the northern Atlantic and northeast Pacific oceans. [14] Areas with a savannah climate in Sub-Saharan Africa, such as Ghana, Burkina Faso, [15 ...
The subtropical highland climate is a climate variety, often grouped together with oceanic climates, which exists in some mountainous or elevated portions of the world in either the subtropics or tropics. Despite the latitude, the higher elevations of these regions mean that the climate shares characteristics with oceanic climates. [17] [18]
Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 cubic kilometres (121,000 cu mi) of water falls as precipitation each year: 398,000 cubic kilometres (95,000 cu mi) over oceans and 107,000 cubic kilometres (26,000 cu mi) over land.

Since the oceans account for 71% of the Earth's surface area, 86% of evaporation (E) and 78% of precipitation (P) occur over the ocean, the oceanic freshwater fluxes represent a large part of the world's freshwater fluxes. [2] There are five major freshwater fluxes into and out of the ocean, namely: Precipitation; Evaporation; Riverine discharge

Over time, the water returns to the ocean, to continue the water cycle. The ocean plays a key role in the water cycle. The ocean holds "97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation". [2]
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
The Caribbean coast, eastward from the Gulf of Urabá on the Colombia–Panama border to the Orinoco River delta, on the Atlantic Ocean (about 4,000 km (2,500 mi)), have long dry periods (the extreme is the BWh climate (see below), characterized by very low, unreliable precipitation, present, for instance, in extensive areas in the Guajira, and ...
