Weather gage be the boat without the weather gage, especially just before the start or when the boat to leeward can point higher into the wind. "Gauge" and "gage" are often used as alternative spellings. To the extent that there is a difference, a "weather gauge" can be a form of meteorological instrumentation for measuring weather quantitatively, such as a rain gauge, thermometer, anemometer, or barometer. A "gage" is a challenge, and hence an entry into battle, though the word is more commonly embedded in the word "engage". Weather gage The weather gage (sometimes spelled weather gauge) is the advantageous position of
Space weather (DSCOVR) satellite is a NOAA Earth observation and space weather satellite that launched in February 2015. Among its features is advance warning of coronal mass ejections. Space weather models are simulations of the space weather environment. Models use sets of mathematical equations to describe physical processes. These models take a limited data set and attempt to describe all or part of the space weather environment in or to predict how weather evolves over time. Early models were heuristic; i.e"., " they did not directly employ physics. These models take less resources than their more sophisticated descendants. Later models use physics
