Simulations based on random multiplicative cascade models are used to investigate the uncertainty in estimates of parameters characterizing the multiscaling nature of rainfall time series. The principal parameters used and discussed are the spectral

The errors introduced into radar estimates of rainfall by making observations at spatial and temporal resolutions that are coarse compared with precipitation systems' characteristic length and time scales are explored in this study. High resolution (

Orographically enhanced rainfall is the dominant climatic feature of the alpine regions of South Island, New Zealand. Most of this rain occurs in strong north-westerly winds although a forecast difficulty exists in that near-saturated north-westerly

A new method of constraining divergent attenuation corrections for weather radar systems is presented. This was motivated by the need for reliable attenuation corrections when making quantitative precipitation estimates using a small, mobile X-band r

There is little doubt that hybrid mesoscale model and image extrapolation systems will eventually become widespread for the nowcasting of precipitation for hydrology and aviation safety. Arguably the final forecast output that is required for these a

The multiscaling statistics of atmospheric surface-layer winds at low wavenumbers above farmland and in the lee of a mountain range were examined using a hot-wire and lightweight cup anemometer. It was found that the horizontal velocity spectra could

A simple potential flow model is developed for airflow over low hills. The model readily allows incorporation of simple rain microphysics so that drop trajectories can be traced in the region of a hill complex. Rainfall intensity variations are found

Air quality in urban areas is often dominated by vehicle emissions but pollutants such as volcanic ash, dust from bush fires and particles from dust storms also contribute. This paper presents a semi-empirical methodology for quantifying the relative

Raingauge data from the 14 July 1987 rainstorm over Montreal are used to underline the reduced errors obtained with a non‐isotropic interpolation scheme. This scheme modifies the geometrical distance between a point and a set of gauges on the basis

A streamflow model of a 4800 km2 rural catchment using distributed rain inputs and infiltration was set up in a computer. Rain inputs were provided in the form of half-hour accumulation maps of real storm events collected by radar over southern Quebe
