Forecasting Space Weather
Forecasting space weather events presents the ultimate challenge to a space physics model. Not only should physical constraints be satisfied, but also practical issues such as timeliness, accuracy, and reliability must be adequately addressed. To address these needs, modern space weather forecasters and users rely on a great variety of space weather models, ranging from simple regressions and e...
متن کاملFORECASTER’S FORUM Budget Cutting and the Value of Weather Services
The authors discuss the relationship between budget-cutting exercises and knowledge of the value of weather services. The complex interaction between quality (accuracy) and value of weather forecasts prevents theoretical approaches from contributing much to the discussion, except perhaps to indicate some of the sources for its complexity. The absence of comprehensive theoretical answers indicat...
متن کاملFORECASTER’S FORUM Weather Forecasting by Humans—Heuristics and Decision Making
The decision-making literature contains considerable information about how humans approach tasks involving uncertainty using heuristics. Although there is some reason to believe that weather forecasters are not identical in all respects to the typical subjects used in judgment and decision-making studies, there also is evidence that weather forecasters are not so different that the existing und...
متن کاملSpace Weather Effects on Communications
An overview of historical and contemporary impacts of the solar and geospace environments on communications systems. Abstract In the last century and one-half, since the invention and deployment of the first electrical communication system – the electrical telegraph, the variety of communications technologies that can be affected by natural processes occurring on the Sun and in the space enviro...
متن کاملSpace Weather Support for Communications
Ionospheric variability (space weather) significantly impacts ground and space-based communications. In essence, the electrically charged particles of the ionosphere (i.e., the partially ionized portion of the atmosphere starting at about 40 nautical miles (nm) above the Earth's surface) can attenuate, totally absorb, reflect, change direction of propagation, and change the phase and amplitude ...
