We have found strong diurnal precipitation cycles over the Gulf Stream
region in summer and over the Kuroshio in the East China Sea in June, middle
of the Baiu-Meiyu rain season (Minobe and Takebayashi, 2014, Climate Dynamic, open access). This paper is highly evaluated by reviewers (thank you!),
as one of them wrote "Thus, his paper expands a new frontier of the
climate in mid-latitude. "
You can see those diurnal cycles in animations.
