Atmospheric circulation
1- Latitudinal features: Hadley cell
The region in which the equatorward moving surface flows converge and rise is known as the intertropical convergence zone, or ITCZ, a high-precipitation band of thunderstorms.Having lost most of its water vapor to condensation and rain in the upward branch of the circulation, the descending air is dry.
Low relative humidities are produced as the air is adiabatically warmed due to compression as it descends into a region of higher pressure.
2- Latitudinal features: Polar cell
During Drosophila oogenesis, the somatic follicle cells form an epithelial layer surrounding the germline cells to form egg chambers. In this process,
follicle cell precursors are specified into polar cells, stalk cells, and main-body follicle cells.
Proper specification of these three cell types ensures correct egg chamber formation and polarization of the anterior-posterior axis of the germline cells.
3- Latitudinal features: Ferrel cell
The Ferrel cell has air motion opposite to planetary rotation. At the surface, this forms the southwesterly prevailing westerlies.
The Ferrel cells and Hadley cells meet at the horse latitudes.
4- Latitudinal features: Walker Circulation
The Walker circulation is the result of a difference in surface pressure and temperature over the western and eastern tropical Pacific Ocean.
The Walker circulation is an ocean-based system of air circulation that influences weather on the Earth.
