The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun. The stream of particles varies in temperature and speed over time. These particles can escape the Sun's gravity because of their high kinetic energy and the high temperature, but do not provide enough heat to change the temperature on the Earth. The atmosphere blocks the Ultraviolet rays that solar winds are composed of and the only evidence they display on Earth are power grids being knocked out and the Northern and Southern lights.
