Latitudinal circulation is a result of the highest solar radiation per unit area (solar intensity) falling on the tropics. The solar intensity decreases as the latitude increases, reaching essentially zero at the poles. Longitudinal circulation, however, is a result of the heat capacity of water, its absorptivity, and its mixing.
The circulation Γ of a vector field V around a closed curve C is the line integral: [3] [4] =. In a conservative vector field this integral evaluates to zero for every closed curve. That means that a line integral between any two points in the field is independent of the path taken.
[57] [31] As a thermally direct circulation, the Hadley circulation converts available potential energy to the kinetic energy of horizontal winds. [58] Based on data from January 1979 and December 2010, the Hadley circulation has an average power output of 198 TW, with maxima in January and August and minima in May and October. [59]
Figure 1: The induced horizontal and vertical circulation patterns induced by a horizontal shear flow at the surface of the fluid. The horizontal shear is indicated by the length and colour density of the arrows at the surface of the fluid. This shear in the velocity at the surface leads to both vertical and horizontal circulation patterns.
A trough is an elongated area of lower air pressure. Since pressure is closely linked to wind, there are often changes in wind direction across a trough. If a trough forms in the mid-latitudes, a temperature difference at some distance between the two sides of the trough usually exists and the trough might become a weather front at some point.
In meteorology, air currents are concentrated areas of winds.They are mainly due to differences in atmospheric pressure or temperature.They are divided into horizontal and vertical currents; both are present at mesoscale while horizontal ones dominate at synoptic scale.

Cumulus clouds can form in lines stretching over 480 kilometres (300 mi) long called cloud streets. These cloud streets cover vast areas and may be broken or continuous. They form when wind shear causes horizontal circulation in the atmosphere, producing the long, tubular cloud streets. [10]
