Walker Cell

There is a zonal atmospheric circulation system associated with this normal ocean condition called the Walker Cell (Eig. 10-7). Evaporation rates are high over the warm pool and warm moist air ascends to great heights (deep convection) producing extensive cloud systems and rain. The Walker Cell is closed by westerly winds aloft and subsidence in the high-pressure zone of the eastern Pacific. 

Walker cell — This was a - Sand battery where the copper electrode is replaced by a graphite or platinized graphite electrode. 

A direct thermally-driven and zonally symmetric large- scale atmospheric circulation first proposed by George Hadley in 1735 as an explanation for the trade winds. It carries momentum, sensible heat, and potential heat from the tropics to the mid-latitudes (30 degrees). The poleward transport aloft is complemented by subsidence in the subtropical high pressure ridge and a surface return flow. The variability of this cell and the Walker cell is hypothesized to be a major factor in short-term climatic change, halocline...

Elephantopus mollis is interesting because it elaborates a series of cytotoxic antitumor germacranolides including molephantinin and phantomolin, which are cytotoxic in vitro and in vivo against Ehrlich ascites carcinoma and Walker 256 carcinosarcoma in rodents (104,105).
