abstract = "The diurnal variation of precipitation at four stations in and
around Manaus (03\◦S, 60\◦W) is studied using hourly
observations for the period 20062011. The rainfall at midforest
stations is 20% greater than that at the city stations, especially
in the afternoon hours. The frequency of rain events varies
substantially with the hour of the day, but the mean intensity of
rain events does not. Daytime [0618 local time (LT)] frequency is
more than two times the nighttime (1905 LT) frequency. The hours
with highest frequency are 1217 LT. The wet season November
through May (NDJFMAM) frequency is approximately three times that
of the dry season June through October (JJASO) frequency at all
hours and at all stations. The diurnal frequency peak in the
afternoon is more pronounced at the forest stations than at city
stations. For smaller intensities of hourly rainfall the afternoon
peaks are very pronounced while larger intensities of rainfall
(15mmh\−1 and above) do not show preference for any hour of
the day. Higher rainfall totals in the rainy season are due to
more frequent rainfall rather than higher intensities of the rain
events. Higher frequencies in the early morning hours close to the
river are possibly due to the river breeze effect.",
