The typical current weathercast display represents the weather symbolically rather than realistically and usually only shows the general air temperature and the location of precipitation.

A method of processing meteorological data to combine meteorological threat products for presentation in a single graphical image is disclosed. The National Weather Service has a network of advanced S-Band radar stations in place at 138 sites in the United States, and is capable of delivering 77 different products to government meteorologists. Weather mass is simulated in three dimensions, i.e., having a bottom and height. This time delay is due in large part to the variety of weather data sources utilized by Miller, which cause delays both in receiving and assimilating the information.In accordance with the invention, meteorological data is received from at least one meteorological data source, and the received meteorological data is processed... These products include; winds aloft, lightning activity and wind shear conditions, such as microburst activity. 5,077,609 discloses an optoelectric system of assistance in attack and navigational missions, which provides a three-dimensional localization of a point of interest for a navigational resetting operation or for a firing control operation. Implementation entails the full or partial occultation of terrain and targets by weather, and vice versa. The present invention is distinguished over the prior art in general, and these patents in particular by providing a weather-casting system for displaying dynamic real time three-dimensional pictorial representations of weather conditions created from meteorological data combined with geographical data.A method of processing meteorological data to combine meteorological threat products for presentation in a single graphical image is disclosed. However, of these 77 products, only 11 are commercially available through contract with several private weather service companies which act as intermediaries between the National Weather Service and the public. Meteorological data including precipitation, cloud cover data, the bottom and top of cloud formations, and reflectivity and velocity of rain droplets in real-time are acquired from C-band Doppler radar, which is combined with NEXRAD data, and the data is digitized and processed to produce a simulated, graphically displayable three-dimensional image of the meteorological data.In accordance with the invention, meteorological data is received from at least one meteorological data source, and the received meteorological data is processed to generate more than one distinct threat products for a given geographic area. These companies charge for the use of these eleven products and, in order to receive the latest radar (NEXRAD) information from a particular site, a private individual or company pays a monthly fee to receive the radar signal. The meteorological data is combined with the geographical data and displayed on a computer display screen, and manipulated by peripheral devices connected with the computer. Also significant is the information that is absent from the conventional weathercast display, such as: (1) the type of precipitation, (2) the strength and location of wind shear, (3) the presence of tornadic signatures showing rapid circular motion, (4) the location of updraft vault, (5) the location of wall clouds, (6) the location of heavy lightning activity, and (7) the wind direction on the ground. Weather maps can be loaded into the system as weather patterns and can be expanded, rotated, and translated. Miller allows for the combination of data from multiple weather sources, but states that his weather images will be at least 20 minutes old by the time they are broadcast. The satellite imagery displayed on the evening broadcast may be anywhere from a half-hour to four ours old. 5,135,397 discloses a 3-D weather simulation system used with a four-channel digital radar landmass simulator (DRLMS) for flight simulators, which integrates culture, elevation, aspect, and weather. 5,583,972 issued to Miller describes a weathercasting system for displaying weather radar information in 3D, such that the viewer can simulate moving through the system to visualize the effects of a weather system at various geographical locations.

The “blue screen” display behind the announcer still usually shows the familiar two-dimensional patchwork rainfall amounts in red, yellow, green and blue.

In some instances, a superimposed satellite display of fluffy cloud patterns is shown moving along over the flat map from an exaggerated height observation point.

The distinct threat products are then combined to create a composite threat product, which may be graphically displayed together with a graphical representation of the geographic area affected by the threat products. There are several patents, which disclose various systems of three-dimensional representation of topographical data and meteorological data for pilots and flight simulators used in pilot training. The combined data is displayed as a three-dimensional graphical representation of weather conditions relative to a selective geographical area.

A system for processing meteorological data for the graphical display of more than one threat product in a single graphical image is also disclosed.receiving a meteorological data corresponding to a geographical region from at least one meteorological data source, the meteorological data comprising a radar reflectivity data and a radial wind velocity data; wherein the combining the rain rate/precipitation threat product, the Vertical Integrated Liquid density/hail threat product, and the gate-to-gate wind shear threat product comprises superimposing the rain rate/precipitation threat product, the Vertical Integrated Liquid density/hail threat product, and the gate-to-gate wind shear threat product over a graphical image representing at least a portion of the geographical region.creating a composite threat product from a meteorological data received from at least one meteorological data source, the meteorological data comprising a radar reflectivity data and a radial wind velocity data; and , wherein the creating the composite threat product comprises processing the meteorological data to derive a rain rate/precipitation threat product, a Vertical Integrated Liquid density threat product, and a gate-to-gate wind shear threat product, and combining the rain rate/precipitation threat product, the Vertical Integrated Liquid density threat product, and the gate-to-gate wind shear threat product.memory for storing a meteorological data corresponding to a geographical region, the meteorological data received from at least one meteorological data source, the meteorological data comprising a radar reflectivity data and a radial wind velocity data; and a processor communicating with said memory to create a plurality of distinct threat products from the received meteorological data, the processor instructed to combine the plurality of distinct threat products to produce a composite threat product capable of being graphically displayed. The graphical representation can be manipulated to allow the viewer to visualize the effects of the weather system at various geographical locations, and from various angles.

further comprising a display device operable to communicate with the processor to display a graphical image of the composite threat product together with a graphical representation of the geographical region affected by the composite threat product., wherein the processing the received meteorological data comprises deriving a rain rate threat product from the radar reflectivity data, deriving a Vertical Integrated Liquid density threat product from the radar reflectivity data, and deriving a gate-to-gate wind shear threat product from the radial wind velocity data. The graphical representation will also provide full volumetric data of the storm, allowing the user to “slice” the storm to view cross sections from various angles, and from various positions, including viewing the storm and a cross section from within the storm itself.

further comprising displaying a graphical image indicative of the composite threat product together with a graphical image indicative of the geographic region affected by the composite threat product.means for receiving meteorological data indicative of a meteorological event affecting a geographic region, the meteorological data comprising a radar reflectivity data and a radial wind velocity data; means for processing the received meteorological data to create a plurality of threat products, the plurality of threat products comprising a rain rate threat product, a Vertical Integrated Liquid density threat product, and a gate-to-gate wind shear threat product; and further comprising a means for associating the composite threat product with a graphical image of the geographic region affected by the meteorological event, and graphically displaying the composite threat product with the graphical image of the geographic region on a display device. One problem associated with combining NEXRAD data with real-time Doppler radar data is the time delay.
