MODELING
4DWX scientists and engineers have teamed to produce a cutting-edge modeling system based on MM5, employing a hybrid real-time observation-nudging scheme and 3D variational assimilation (3DVAR). >more
AUTO-NOWCASTING
The primary role of the nowcast environment is to collect weather data; execute algorithms for producing a combined thunderstorm forecast; and provide a graphical display tool for viewing the various datasets. >more
TOOLS
The "main engines" of the 4DWX system are the modeling and auto-nowcasting capabilities, but a wide range of tools accompany a typical 4DWX system implementation; providing the user with clear interfaces to the underlying data, the configuration of the various models, and their output products. >more
DISPLAYS
Intuitive visualization of 4DWX data and products is critical to supporting forecasting operations. A number of displays have been created to meet these needs. >more
HARDWARE
NCAR has partnered with three commercial providers of hardware systems for running the models and other 4DWX subsystems. >more
