One of the challenges of living and working in the Great Basin is the variable climate. However, there has been surpisingly little research on the effect of weather variation on rangeland vegetation. The difficulty in manipulating weather is part of the reason for the lack of prior research. One can attempt to document year-to-year changes in vegetation and relate the changes. /bg - As a result of climate change, rainfall regimes became more extreme over the course of the 20th century, characterised by fewer and larger rainfall events. Such changes are expected to continue throughout the current century. The effect of changes in the 5 temporal distribution of rainfall on ecosystem carbon fluxes is poorly understood, with most available information.
In this study, the results of a series of experiments are reported, summarizing the soil loss and runoff response from a = m area to different rainstorm regimes, slope steepnesses, subsurface soil water pressures, and surface roughnesses under controlled laboratory. This study investigates the effect of rainfall temporal distribution pattern within a storm event on soil erosion rate and the possibility of using rain power type model for rainfall erosivity. Various rainfall distribution patterns, simulated by rainfall simulator, were used on m 2 plot of silica sand and loam soil with a minimum of three replications.
Effectiveness of rainfall can also be assessed in terns of monetary returns. This is a rather complicated analysis. The returns depend upon the type of production, use of other inputs such as fertilizers, plant protection measures, soil fertility, weather parameters other than rainfall, infra-structure developed in the area, farm management efficiency and market prices. objective of the study was to evaluate the effects of some aspects of rainfall trends in Makurdi, enumerate the implications of these trends on soil and crop management practices and identify majors that will ameliorate negative implications of rainfall trends .

Studies of the oreigenic effect on the areal fine structure of rainfall distribution. Meteorological Institute, Uppsala University, report no. Bergström S, Carlsson B, Gardelin M, Lindström G, Pettersson A, Rummukainen M.
Cited by: Rainfall analysis is important to managing water resources. Mean rainfall is usually used to calculate the spatial rainfall status of a region and is the input into various rainfall-runoff models. However, this method relies on an adequate raingauge network. This study identifies the effects of raingauge distribution based on estimation results of areal rainfall using the Thiessen polygon and Cited by: [ Book: ] View online (access conditions) At 11 libraries Studies of the oreigenic effects on the areal fine structure of rainfall distribution Bergeron, Tor, [ Book: ] At Nat Met Library.
This resource is very relevant to your query (score: 78,). The present paper aims to study the effect of rainfall intensity on groundwater level. The study is based on the field observation at the Donher well station in Central Taiwan and rainfall data measured by seven rain-gauge stations nearby the Donher well station.
The influence of rainfall temporal distribution and surface watershed is also Cited by: This study used the optimal estimation method of areal rainfall to identify the effects of raingauge distribution and representative sites on a watershed. The optimal method is the. Studies of the oreigenic effects on the areal fine structure of rainfall distribution.

De tropiska orkanernas problem: installationsföreläsning i Uppsala den april The individual effects of mean rainfall, storm duration, and other storm factors were small and erratic in behavior when the foregoing analytical technique was used.
Basin area had a small but consistent effect upon the time distribution. The derived relations are applicable to the Midwest and other areas of similar climate and topography. Results of the model application to a bell-shaped solitary hill are presented and compared with previous theoretical studies and field observations in the Welsh hills.
areal fine structure of. The application of 21 pluviometers over the whole area of Łódź, Poland, enabled an examination of areal distribution of intense rainfalls during – On the basis of collected data the distribution of rainfall intensity was analysed and a circular zone model with exponential shape in all directions has been proposed for describing rain storms.
The annual rainfall data is analyzed and the variation in distribution over the area is studied with the statistical parameters. The best fit distribution method is found using various plotting position and probabilistic methods.
0 In dry farming areas, where rainfall is the only source of water for crops, changes in both quantity and distribution of rainfall during the year could affect the economy of an area. Inter-annual variability makes it difficult to assess rainfall variability, especially in areas with Mediterranean climate.
In this paper, interannual rainfall variations in the Alt Penedès region were evaluated. The completed data file of 47 station means shows a complex pattern of rainfall distribution (Fig.
The effect of altitude can be clearly discerned but a secondary effect is that of gradually decreasing rainfall totals from south-west to north-east across the area in the direction of the prevailing rain bearing south-westerly winds.
The objective of this study was to determine the effect of shortage and uneven distribution of rainfall on yield and yield variability in different genotypes of blue lupin.
METHODS The results for this study were derived from ﬁ eld exper-iments conducted in the years – at the Agricul. Therefore, to understand the fine structure of rainfall, 1‐year (April to March ) rain data was measured with 1‐min integration time and plotted, as seen in Figure 5.
For these measurements, a tipping bucket arrangement of diameter 20‐cm with a calibration of ‐mm per tip was interfaced with a programmable data logger, which. determine the effect of climatic variability on rainfall distribution pattern and (iii) analyze the relationship between the arable crops output and the annual rainfall distribution in the study area.
Hypothesis of the Study. Ho: There is no significant relationship between the annual output of arable crops production and the annual rainfall.
The shape and scale parameters are then regionalized and hence it becomes possible to find the parameter values at any desired location within the study area and then to generate synthetic sequences according to the gamma distribution.

Suva is located on the southeastern part of Fiji’s main island, Viti Levu (Figure 1) and the main measurement site.The study analyses annual and seasonal rainfall variability and identifies the relationship between rainfall and crop production in the Lawra district of Ghana.
It also suggests adaptation techniques/measures to mitigate the effects of rainfall uncertainties. MATERIALS AND METHODS Description of the study area.Geographical location of the study area. The sample site on the west side of the investigated dust source in Mongolia is shown on the map.
