While Earth's weather reports center on precipitation, temperature, wind direction and velocity, and humidity, space weather forecasts attempt to predict activity that occurs on the sun -- and how the...
太阳瞬变爆发活动(日冕物质抛射CME等)及其伴随的行星际激波具有强烈的空间天气效应,因此预报它们传播到地球轨道的时间是空间天气预报的一个重要组成部分。近期,中国科学院国家空间科学中心空间天气学国家重点实验室赵新华副研究员和冯学尚研究员自主开发出了到达时间预报的第二代激波传播模型(SPM2),该模型基于爆炸波传播解析,使用扰动初始时刻的观测参数(初始激波速度、背景太阳风速度等)作为输入,能对相应行星...
ANN ARBOR—A comet-bound spacecraft that spent more than two years in a deep sleep mode woke up on Jan. 20 to begin the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice...
This paper describes the space weather effects of a major CME which was accompanied by extremely violent events on the Sun.The signatures of the event in the interplanetary medium (IPM) sensed by Ooty...
We discuss the effects of certain dynamic features of space environment in the heliosphere, the geo-magnetosphere, and the earth’s atmosphere. In particular, transient perturbations in solar wind plas...
Ionospheric response to the space weather event of 18 November 2003 -- An investigation.
This paper describes the space weather effects of a major CME which was accompanied by extremely violent events on the Sun. The signatures of the event in the interplanetary medium (IPM) sensed by Oot...
We discuss the effects of certain dynamic features of space environment in the heliosphere, the geo-magnetosphere, and the earth™s atmosphere. In particular, transient perturbations in solar win...
