Weather Radar Echo Extrapolation with Dynamic Weight Loss

Image Sequence Retrieval for Forecasting Weather Radar Echo Pattern

A novel method is proposed to retrieve image sequences with the goal of forecasting complex and timevarying natural patterns. To that end, we introduce a framework called Memory-Based Forecasting; it provides forecast information based on the temporal development of past retrieved sequences. This paper targets the radar echo patterns in weather radar images, and aims to realize an image retriev...

Wind observations with Doppler weather radar

Introduction Weather radars are commonly employed for detection and ranging of precipitation, but radars with Doppler capability can also provide detailed information on the wind associated with (severe) weather phenomena. The Royal Netherlands Meteorological Institute (KNMI) operates two identical C-band (5.6 Ghz) Doppler weather radars. One radar is located in De Bilt and the other one is loc...

Localization Methods of Weighted Centroid of dBZ on Weather-Radar Echo Maps in Vector Format

Fast generation of weather-radar echo maps in vector format and accurate localization of weighted centroid of dBZ (dBZ stands for decibels of reflectivity of a radar signal reflected off a remote object) are the basis of studying the characteristic tracking algorithms which are based on the vector echoes. The authors principally studied the approach to generating the vector echo map, and discus...

The Danish weather radar network

The Danish Meteorological Institute (DMI) operates four cband radars for weather monitoring. Three of these radars are doppler and were purchased from Electronic Enterprise Corporation (EEC) in the last 2 – 4 years. The fourth radar is an older non-doppler radar manufactured by Ericsson of Sweden and is situated on the island of Bornholm in the Baltic Sea. Geographical location of the radar sit...
