所在單位:德國(guó)HZG海岸帶研究所(前所長(zhǎng))
報(bào)告時(shí)間:2018年11月20日14:30-15:30

漢斯·馮·斯托奇已經(jīng)出版了17 本書 和無(wú)數(shù)文章。他是氣候、環(huán)境與政策雜志和氣象(雜志),海洋與湖沼,由波蘭科學(xué)院的全球變化計(jì)劃出版的“全球變化論文IGBP”,網(wǎng)格氣候變化,地理年報(bào),羅馬尼亞氣象日?qǐng)?bào),的咨詢審查委員會(huì)成員,以及HZG學(xué)校環(huán)境研究(由斯普林格出版社系列發(fā)表)的承辦者,以及AGU大氣科學(xué)節(jié)的通訊員。他創(chuàng)造了“降尺度”方法-利用統(tǒng)計(jì)多樣性方法對(duì)氣候變化情景建設(shè)的首例。另外在降尺度領(lǐng)域:介紹了譜逼近方法,為重建幾十年的區(qū)域性氣候情景。漢斯·馮·斯托奇是最早證實(shí),區(qū)域數(shù)值模型試驗(yàn)也需要信號(hào)與噪音分析,就像全球模擬試驗(yàn)一樣。在歐洲評(píng)估了風(fēng)暴及海洋(涌浪、潮波)的影響。同時(shí)次綜觀風(fēng)暴也被解決,尤其在它的極低點(diǎn)。實(shí)現(xiàn)了用于常規(guī)分析和預(yù)報(bào)的克勞斯哈塞爾曼的主要振蕩模式抽象概念。
內(nèi)容簡(jiǎn)介:
The internally generated variability in the climate system, which is unrelated to any external factors, can be conceptualized as “noise”. This noise is a constitutive element of high-dimensional nonlinear models of such systems. In a three-layer nested simulation, which is forced by climatological (periodic) atmospheric forcing and includes an (almost) global model, a West-Pacific model, and South China Sea (SCS) model, we demonstrate that such “noise” builds also ocean models. They generate variability by themselves without an external forcing. The “noise” generation intensifies with higher resolution, which favors macroturbulence.
