A multicell thunderstorm cluster affected parts of the Breckland region in south Norfolk on afternoon 16 August 2020, producing as much 240mm rain. detailed mesoanalysis is constructed to analyse meteorological conditions present using conventional observations, reanalysis and privately owned automatic weather station observations. While instantaneous rain rates observed are not unprecedented, ...

A watershed management program is usually based on the results of watershed modeling. Accurate modeling results are decided by the appropriate parameters and input data. Rainfall is the most important input for watershed modeling. Precipitation characteristics, such as rainfall intensity and duration, usually exhibit significant spatial variation, even within small watersheds. Therefore, proper...

As a thunderstorm approaches a fixed asset (90% of the time) where people are located, VHF cloud lightning mapping provides 10s of minutes of lead time before the first cloud-to-ground strokes reach this asset. At times when a thunderstorm develops directly over the fixed asset (~10% of the time), the cloud flash detection efficiency exceeding 90% maximizes lead time during thunderstorm growth ...

the part of precipitation that directly meets the water requirements of a plant, is termed the effective rainfall. effective rainfall estimation methods consist of: direct measurement, empirical methods, and soil-water balance modeling. due to the high costs of measurements and storing devices such as lysimeter, empirical and balance methods are most commonly used to estimate the effective rain...

australian rainfall is related with numerous key climate predictors namely el-nino southern oscillation (enso), indian ocean dipole (iod) and southern annular mode (sam). some studies have tried to discover the effects of these climate predictors on rainfall variability of different parts of australia, particularly western australia, queensland and victoria. nonetheless, clear association betwe...

thunderstorm is one of the most dangerous phenomena in aviation because the greatest number weather hazards such as icing, turbulence, wind shear, lightning hail are combined in one single source, the thunderstorm. spatial characteristics of thunderstorms which can be associated with irreparable outcomes are known by most of the forecasters. tornadoes, microbursts, very strong winds and flash f...
