Declination studies reveal significant influences on climate in the formation of air tides.
The phenomenon of the effects of declination on the jet stream of the eastern Pacific can be related to the work of a Chinese researcher LI Guoqing of the Institute of Atmospheric Physics, in Beijing. The paper entitled, 27.3 and 13.6 day Atmospheric Tide and Lunar Forcing on Atmospheric Circulation [PDF] researches the influence of the earth’s length of day (LOD) in relation to the geopotential height of the 500mb fields in the eastern Pacific and the declination of the moon. It was found that there is an alternating increase and decrease in geopotential height in the eastern Pacific in approximately seven day cycles that are keyed not to the phases of the moon but to the declination of the moon. The different modes of the declination response were that during the times when the moon was at a maximum declination north or south there was a corresponding speeding up of the earth’s rate of diurnal rotation according to measurements done with the atomic clock in France. The speeding up of the earth had the effect of shifting air masses to the west in the eastern Pacific.
