Bleak forecast for space weather

Cloudy forecast for weather satellite data.

IN THE NEWS FOCUS STORY “WEATHER forecasts slowly clearing up” (9 November, p. 734), R. Kerr nicely summarizes how the growing improvement in prediction is coming from a focus on “more computer power, the assimilation of radar observations, and more physically realistic models.” He emphasizes that better assimilation of satellite data is a key element of improved forecasting. Unfortunately, the...

Weather Derivatives and Seasonal Forecast

The purpose of this paper is to incorporate the CPC (Climate Prediction Center) seasonal forecast in the temperature process so that conditional means and conditional variances of both the temperature and the CDD (Cooling Degree Day) may be redetermined in accordance with the seasonal forecasting probabilities. Under the Gaussian property of the underlying process, the prices of the CDD options...

Multilingual Weather Forecast Generation System

The MLWFA (Multilingual Weather Forecasts Assistant) system will be demonstrated. It is developed to generate the multilingual text of the weather forecasts automatically. The raw data from the weather observation can be used to generate the weather element chart. According to the weather change trend, the forecasters can directly modify the value Of the element on the chart, such as the center...

Space Weather Forecast Predicts Changes in Sun-Earth Space Environment by Using Observation Data

GPS=GLONASS-based TEC measurements as a contributor for space weather forecast

Space weather monitoring and forecast require a permanent monitoring of the ionospheric state on global scale. The world-wide use of global navigation satellite systems such as GPS and GLONASS o7ers the unique chance for a permanent monitoring of the total ionization (total electron content—TEC) of the global ionosphere=plasmasphere up to about 20000 km height. In this study we turn our attenti...
