Studies of sporadic‐ E data have shown that both the altitude and density of E S layers vary in lunar time. Possible sources of the lunar effect are motions of the E S layer produced by the electrostatic field associated with the lunar ionospheric current system, and wind shears in the lunar atmospheric tide. From studies of lunar atmospheric tides and the lunar ionospheric dynamo, values of the electrostatic field and wind shear may be estimated. Simple models are used to determine the effects of these electric‐field and wind distributions on E S layers, and the results are compared with the observed lunar variations in E S .
