翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Potential predictability ： ウィキペディア英語版 Potential predictability The term potential predictability is used in the context of weather forecasting to describe the extent that the future weather can be predicted ''in principle'', i.e., it describes the proportion of variance in the weather that arises from systematic factors rather than random noise. ==Mathematical formalization== Denote by $\backslash sigma$ the standard deviation in weather outcomes, so that $\backslash sigma^2$ is the variance in weather outcomes. Of this, denote by $\backslash sigma\_\backslash nu^2$ the ''internally generated'' variance component and by $\backslash sigma\_\backslash varepsilon^2$ the ''unpredictable noise'' component. We have:〔 $\backslash sigma^2\; =\; \backslash sigma\_\backslash nu^2\; +\; \backslash sigma\_\backslash varepsilon^2$ The potential predictability variance fraction (ppvf) is defined as: $p\; =\; \backslash frac\; =\; \backslash frac$ The signal to noise ratio is defined as: $\backslash gamma\; =\; \backslash frac$ $p$ and $\backslash gamma$ can be computed from each other: $p\; =\; \backslash frac\backslash qquad\; ,\backslash qquad\; \backslash gamma\; =\; \backslash frac$ We have . Small values of $p$ indicate that the signal is small, and that the weather is inherently unpredictable. Values of $p$ close to 1 suggest that the weather is ''potentially'' predictable, even if current weather prediction methods do not predict it successfully. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Potential predictability」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
