20450 results about "Atmospheric sciences" patented technology

Atmospheric science is the study of the Earth's atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes (both long and short-term) that define average climates and their change over time, due to both natural and anthropogenic climate variability. Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important. Atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets and natural satellites of the solar system.

System and method for inland river bridge zone shipborne sailing active collision prevention

The invention provides a method for inland river bridge zone shipborne sailing active collision prevention. The method comprises the steps of collecting hydrological information, meteorological information and ship information of nearby ships and the ship, automatically updating river map information on line, and performing data storage; forecasting tracks of the ship and other ships according to obtained track information of the ship and other ships by combination with the real-time hydrological information and the meteorological information, and obtaining track information of every ship; calculating the nearest meeting distance and the nearest meeting time of the ship and a target object according to the obtained track information; and giving collision accident pre-warning and active collision prevention suggestions according to the nearest meeting distance and the nearest meeting time of the ship and the target object. According to the method, by predicating ship sailing situations, the shortcoming that an existing ship assistance navigation device cannot accurately obtain the position of the target object, and the nearest meeting distance and the reaching of the nearest meeting distance cannot be pre-judged more accurately is overcome.
