Implementation of the Wang & Sheeley Solar Wind Model
Abstract
LONG-TERM GOAL. The goal is to make available on a routine basis accurate predictions of the quasi-steady component of the global solar wind outflow. These predictions have immediate utility for space weather applications and are of direct relevance to the space science community in developing its understanding of the propagation of solar disturbances throughout the heliosphere. SCIENTIFIC OBJECTIVES. The objective is to bring the existing research version of the Wang and Sheeley (1990, 1992) global solar wind model into routine daily use in the NOAA/SEC forecast center and to make the results readily accessible to the broader research and space-environment user community through the internet and other channels. For the first time, the performance of a global solar wind model will be subjected to rigorous verification procedures, which will form the baseline for tracking future improvements in capability. The three-dimensional map of the interplanetary environment provided by the model is currently the best available real-time assessment of the global distribution of solar wind speed and magnetic field polarity. From the model output, more enlightened predictions of geomagnetic activity can be made and observations of propagating interplanetary disturbances and evolving heliospheric structure can be interpreted more meaningfully.
