Overview

Joint Project for Space Weather Modeling is a nationwide collaboration for space weather modeling in Japan. The project proceeds as a part of the Grant-in-Aid for Creative Scientific Research "The Basic Study of Space Weather Prediction" (17GS0208, Head Investigator: K. Shibata) from the Ministry of Education, Culture, Sports, Science, and Technology of Japan

  1. What is Space Weather?

    The Sun, which is the primary driver of the terrestrial environment, affects the electromagnetic environment of the Earth. In particular, solar eruptions initiated by solar flares and/or coronal mass ejections (CME) sometimes cause severe damage to satellites, communication systems, and astronauts in orbit through the propagation of shock waves in the solar wind and the impact of solar energetic particles. The physical condition of the space environment is called space weather. Forecasting space weather is becoming into an important issue for modern society because the modern infrastructures, such as satellites, communication systems, and power grids, are vulnerable to space weather,

  2. Objective

    The objective of the Joint Project for Space Weather Modeling is to improve the predictability of space weather in terms of state-of-the-art technology for numerical simulations and high-precision observations. In particular, our goal is to develop a novel methodology for the prediction of solar flares and for the evaluation of the solar impact on the Earth's magnetosphere.

  3. Model

    Our model consists of several regional models that can compute the initiation and propagation of solar eruptions from the Sun to the Earth. The regional models for solar active regions, the solar corona, inter-planetary space, and the Earth's magnetospheric dynamics have been developed and are designed to be interlocked with each other. Also, the model for particle acceleration is investigated for the modeling of solar energetic particles. Refer to this link for details on the regional models.
