46 results about "Weather warning" patented technology

A weather warning generally refers to an alert issued by a meteorological agency to warn citizens of approaching dangerous weather. A weather watch, on the other hand, typically refers to an alert issued to indicate that conditions are favorable for the development of dangerous weather patterns, although the dangerous weather conditions themselves are not currently present.

Dual-polarization radar observation based method for improving thunderstorm weather warning and forecasting accuracy

The invention belongs to the field of radar observation based weather forecasting and discloses a dual-polarization radar observation based method for improving thunderstorm weather warning and forecasting accuracy. X waveband dual-polarization weather radar parameters are utilized. On the basis of quality control on data including phase defolding, filtering and attenuation correction and based ona fuzzy logic algorithm, environment temperature limits of sounding data are introduced for identification of multiple hydrometeors in a thunderstorm body. Comparatively detailed analysis is performed on evolution characteristics of the hydrometeors in clouds in two aspects including horizontal distribution and perpendicular distribution during a typical thunderstorm body development process according to an inversion result. Finally, a micro-physical concept model during the thunderstorm body evolution process is established and the structure and the evolution features of the thunderstorm body are acquired. The method provided by the invention facilitates recognition of hydrometeor distribution and a microphysical process in the typical thunderstorm body and provides a quantitative and direct technical support for thunderstorm weather warning and forecasting.
