Freezing rain is a major atmospheric hazard in mid-latitude nations of the globe. Among all Canadian hydrometeorological hazards, freezing rain is associated with the highest damage costs per event. Using synoptic weather typing to identify the occurrence of freezing rain events, this study estimates changes in future freezing rain events under future climate scenarios for south-central Canada....

Rainfall is an extremely variable parameter in both space and time. Rain gauge density is very crucial in order to quantify the rainfall amount over a region. The level of rainfall accuracy is highly dependent on density and distribution of rain gauge stations over a region. Indian Space Research Organisation (ISRO) have installed a number of Automatic Weather Station (AWS) rain gauges over Ind...

APRIL 2003 | C ategorical, or conditional, statistics quantify the skill in the prediction of the occurrence of rain, and are based on the familiar 2 × 2 (yes/no) contingency table. Given a set of matched rain forecasts and observations, the contingency table is a matrix giving the frequencies of predicted and observed rain occurrence and nonoccurrence. “Hits,” H, are correct predictions of rai...

Quantitative precipitation estimation and rainfall monitoring based on meteorological data, potentially provides continuous, high-resolution and large-coverage data, are of high practical use: Think of hydrogeological risk management, hydroelectric power, road and tourism. Both conventional long-range radars and rain-gauges suffer from measurement errors and difficulties in precipitation estima...

A revised Bayesian algorithm for estimating surface rain rate, convective rain proportion, and latent heating profiles from satellite-borne passive microwave radiometer observations over ocean backgrounds is described. The algorithm searches a large database of cloud-radiative model simulations to find cloud profiles that are radiatively consistent with a given set of microwave radiance measure...

Tropical Rainfall Potential (TRaP) forecasts provide estimates of 24 h rainfall accumulation in landfalling tropical cyclones based on the advection of a field of satellite-estimated precipitation. Validation of TRaP forecasts for five Australian tropical cyclones during the 2003-04 season showed significant skill in predicting heavy rainfall. The predictions of maximum rain at landfall compare...
