The large-scale tropical overturning circulation with rising motion near the equator and sinking in the subtropics is the
Hadley cell
The general circulation of the atmosphere in each hemisphere is described by three cells: the Hadley cell (0–30°), the Ferrel cell (30–60°) and the Polar cell (60–90°). The Walker cell is an east–west (zonal) circulation along the equator.
In the tropics, intense solar heating makes air rise near the equator in the Intertropical Convergence Zone (ITCZ). This air moves poleward aloft, cools and sinks at about 30° latitude, forming the subtropical high-pressure belts, and returns to the equator as the trade winds.
This thermally direct, meridional (north–south) overturning loop of the tropics is the Hadley cell. The Ferrel cell is an indirect mid-latitude cell, the Polar cell lies at high latitudes, and the Walker cell runs zonally across the equatorial Pacific, not between the equator and the subtropics.
Hence, the answer is Hadley cell.

A building is to be founded on a clay stratum. The water table is practically at ground surface level. Laboratory test show that the unit weight of the soil is r = 20 kN/m3 and classify the soil as a firm clay. The uniaxial compressive strength is qu = 150 kN/m2. Suppose that the footing will be square, 2 m wide, and the foundation depth will be 2 m below the ground surface, calculate the ultimate bearing capacity.
In a soil mechanics and engineering project, a stratigraphic column below the horizontal ground level of a wide valley is formed by 3 m of coarse gravels over a 12 m clay deposit. Below the clay is a highly permeable fractured sandstone. The water table in the gravel layer is 0.6 m below ground surface. In the sandstone substratum artesian condition with a piezometric height of 6 m above ground level exist. The gravel layer is very permeable and assumed to be hydrostatic. Determine the pore water pressure distribution.
