Processing of Doppler radar radial winds for data assimilation

Atmospheric wind field is 3-dimensional and variable over time and space. Doppler radar measures one component of the wind vector, ie. the radar radial component. For complete description of the wind field simultaneous measurements should be made with three Doppler radars. Usually only one radar is available and the availability of the other two radars is compencated by simplifying assumptions ...

Use of Wind-Shear Displays for Doppler Radar Data

The usefulness of displaying vertical wind shear on a radar range height indicator is demonstrated. Fine structure in the pattern of shear is shown to be helpful for inferring general flow patterns and the occurrence of billows due to shearing (Kelvin–Helmholtz) instability. Corresponding author address: Prof. Keith A. Browning, Joint Centre for Mesoscale Meteorology, Department of Meteorology,...

Validation of the NWP Model HRM with Groundbased GPS Data

The atmospheric water vapor is a very important variable for the hydrological cycle and for short term numerical weather prediction. Groundbased GPS data are applied to validate the vertically integrated water vapor (IWV) as derived with the HRM model (High resolution Regional Model) of the German Weather Service (DWD) within the BAL.TEX (Baltic Sea Experiment) region. Data of the PIDCAP period...

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...

covariance functions for vector wind analyses using Doppler - radar radial - velocity observations

A two-dimensional form of cross-covariance function between the radar radialand tangential-components (with respect to the direction of radar beam) of background wind errors is derived. Like the previously derived auto-covariance function for the radial-component, this cross-covariance function is homogeneous but non-isotropic in the horizontal. The autoand cross-covariance functions are used w...
