        Erosion and precipitation rates vary over an order of magnitude across the range with maxima of mm yr-1 and m yr-1, respectively, with both maxima Cited by: In recent years, regional frequency analyses based on annual maximum series (AMS) methods have found wide application, while partial duration series (PDS) methods have not. Typically, the generalized extreme value (GEV) distribution has fit annual maxima, corresponding to generalized Pareto (GPA) distributed threshold exceedances.

Regional Analysis of Annual Precipitation Maxima in Montana. By Charles Parrett. Abstract. Dimensionless precipitation-frequency curves for estimating precipitation depths having large recurrence intervals were developed for 2- 6- and hour storm durations for three homogeneous regions in by: Within each homogeneous region, at-site annual precipitation maxima were made dimensionless by dividing by the at-site mean and grouped so that a single frequency curve would be applicable for each duration.

L-moment statistics were used to help define the homogeneous regions and to develop the dimensionless precipitation- frequency curves. Get this from a library.

Regional analysis of annual precipitation maxima in Montana. [Charles Parrett; Montana. Department of Natural Resources and Conservation.].

Regional analyses of precipitation data were conducted using an index flood type methodology and probability weighted moments parameter estimates for the generalized extreme value distribution. Annual maximum series data were collected at stations for durations of 2 and 6 hours and at stations for the 24‐hour by: Abstract.

L-moment procedures are applied to develop regional rainfall annual maxima (maximum h rainfall occurring annually), considering complex physiographic and hydroclimatological features and weather processes as attributes influencing regional homogeneity.

Capability of L-moment procedures in breaking down large areas into coherent and homogeneous sub-regions is by: back to Home Page. Western Regional Climate Center, [email protected]   The analysis uses the University of Washington’s (UW’s) gridded precipitation (Maurer et al.

).The dataset uses the Parameter-Elevation Regressions on Independent Slopes Model (PRISM; Daly et al. ) corrections for systematic elevation effects on precipitation climatology and provides observation-based precipitation on an eighth-degree grid that covers all of the contiguous Cited by: Based on these extremes, which represent more accurately heavy precipitation than annual maxima, we form time series of their annual frequency and mean annual magnitude.

The analysis offers new insights and reveals (1) global and zonal increasing trends in the frequency of extremes that are highly unlikely under the assumption of stationarity Cited by: The approach produces ARF that decrease more rapidly than those from TP Furthermore, the ARF from the approach decay rapidly with increasing recurrence interval of the annual-precipitation maxima.

The annual precipitation totals are averages based on weather data collected from to for the NOAA National Climatic Data Center. You can jump to a separate table for each region of the state: Northwestern, Southwestern, South - Central and Eastern Montana.

The main purpose of the research carried out was to identify trends in the annual maximum daily rainfall series – Pdma, from the Portuguese, Precipitação diária máxima annual – somehow denoting theFile Size: KB.

The GEV model is well suited for the prediction of heavy rainfall events although there are uncertainties beyond the 90th percentile. The annual maxima of daily precipitation will also increase by and could be of benefit to the ecosystem services and socioeconomic activities in the Mono river basin but could also be a : Ernest Amoussou, Hervé Awoye, Henri S.
