On a distribution of weather cycles by length

In the paper a weather cycle is defined as the combination of a wet (dry) spell with the successive dry (wet) spell. On the assumption that the lengths of wet and dry spells are independent and obey geometric distributions, the distribution function of the lengths of weather cycles is deduced and tested against observational data for Tel Aviv. The peak frequency of weather‐cycle lengths at Tel Aviv is found to be at about 4 days.
