Analysis of 4973 Etesian cases that took place over 90 years (1892-1981) reveals a possible solar signature in the troposphere. The signature consists of a characteristic tendency of the Etesian cases to build predominant peaks on the 7th--8th solar rotation days (Bartel days). Further analysis of the data in various solar activity levels showed the possible solar control of the Etesian's occurrences to be significant in the epoch of the solar maximum but weak in the intermediate years and insignificant in the epoch of solar minimum of solar angles 13-21. Keeping in mind that in most cases of solar-weather events the coupling was detected mainly in winter, a possible solar signature on the Etesians, appears to be rare case where a summer weather effect would be affected by the sun.
