Changepoint detection in daily precipitation data
Environmetrics, 2012This paper introduces a method to identify an undocumented changepoint time in a daily precipitation series. A two‐state Markov chain is used to induce dependence in the precipitation amounts; our dynamics allow for seasonality in the daily observations, a structure inherent to many nonequatorial region series.

On the Conditional Distribution of Daily Precipitation Amounts
Monthly Weather Review, 1980Abstract Possible conditional dependence of the distribution of daily precipitation amounts on the occurrence of precipitation on the preceding day is examined. Test results based on 25 years of data at 30 stations in the conterminous United States show that such dependence exists only in the winter season over the Pacific Northwest.

Objective prediction of daily precipitation and cloudiness
Journal of Geophysical Research, 1965The relation between present weather and concurrent daily 700-mb circulation is studied for the winter season in the United States. All weather data are averaged within 40 climatologically homogeneous circles and expressed as a numerical index giving the proportion of precipitation or cloudiness within each circle at map time.

Stochastic modeling of daily precipitation in China
Journal of Geographical Sciences, 2004A stochastic model for daily precipitation simulation in China was developed based on the framework of a ‘Richardson-type’ weather generator that is an important tool in studying impacts of weather/climate on a variety of systems including ecosystem and risk assessment.

Basic structure of daily precipitation series
Journal of Hydrology, 1983Abstract Daily precipitation series exhibit intermittency, periodicity and stochasticity. To show it, three stations are used as examples. All series parameters, even descriptors of intermittency (probability of zero precipitation, run-lengths of zero and non-zero values), are highly periodic.

Atmospheric circulation and daily precipitation in Wales
Theoretical and Applied Climatology, 1992Daily precipitation affinity areas are established for Wales by means of S-mode Principal Components Analysis (PCA) and Cluster Analysis, using data for the autumn-winter (September-January) period, 1982–87, subset according to surface wind direction.

Statistical model for daily precipitation
1984Daily records of precipitation measured in Modena (Po Plain in Italy) since March 1830, were analyzed in the framework of a stochastic bivariate model. The following stochastic variables were chosen: q, equivalent height of water precipitated during the wet day; d, number of dry days which precede the wet day.

Trends in Total Precipitation and Frequency of Daily Precipitation Extremes over China
Journal of Climate, 2005Abstract Based on a newly developed daily precipitation dataset of 740 stations in China and more robust trend detection techniques, trends in annual and seasonal total precipitation and in extreme daily precipitation, defined as those larger than its 95th percentile for the year, summer, and winter half years, have been assessed for the

Variability of daily precipitation over Nigeria
Meteorology and Atmospheric Physics, 2014This study identified coherent daily precipitation regions in Nigeria by analyzing the spatial and temporal homogeneity of daily precipitation; investigating the dependence of wet day amount (WDAMT) and percentage of wet day (PWD) on latitude, longitude, elevation and distance from the ocean and finally regionalizing the daily precipitation stations ...
