Characteristics and mechanisms of the diurnal variation of winter precipitation in Taiwan

This study examines the spatio-temporal characteristics of the climatological diurnal winter precipitation in Taiwan. The figure shows the phase diagram depicting the timing of the occurrence of the maximum values of the winter precipitation during the day over Taiwan. It is noted that the timings of the maximum values of the diurnal precipitation in Taiwan exhibit clear east?west regional differences, with night-time maxima over eastern Taiwan but early morning maxima over western Taiwan. Possible formation mechanisms are also discussed.
