概率温度预报:四种扩散-回归模型的比较
Probabilistic temperature forecasting: a comparison of four spread-regression models
摘要:
扩散回归是线性回归的扩展,允许包含包含方差信息的预测因子。它可用于从天气预报集合中获取信息,并对未来温度进行概率预测。有许多方法可以详细地制定扩散回归。我们进行实证比较的四个最明显的方法,适用于校准一年的ECMWF温度预测伦敦希思罗机场。
英文摘要:
Spread regression is an extension of linear regression that allows for the inclusion of a predictor that contains information about the variance. It can be used to take the information from a weather forecast ensemble and produce a probabilistic prediction of future temperatures. There are a number of ways that spread regression can be formulated in detail. We perform an empirical comparison of four of the most obvious methods applied to the calibration of a year of ECMWF temperature forecasts for London Heathrow.
