North China has undergone a severe drying trend since the 1950s, but whether this trend is natural variability or anthropogenic change remains unknown due to the short data length.This study extends the analysis of dry-wet changes in North China to 1900-2010 on the basis of self-calibrated Palmer Drought Severity Index (PDSI) data.

The possible influences of two types of ENSO (i.e., the canonical ENSO and the ENSO Modoki, EM) on the Hadley circulation (HC) during the boreal spring are investigated during 1979～2010.
本文基于海气多要素资料,对比分析了两类El Nino事件(中部型,简称CP;东部型,简称EP)发展年的印度洋的海气异常特征.结果表明,两类El Nino事件的发展年均有IOD出现的可能,大多数EP事件期间有IOD出现,CP期间也可能出现IOD,但与EP相比,CP与IOD的关系并不稳定,热带太平洋-印度洋的海温异常的强度明显较弱.
The parameters of tropopause derived from high vertical resolution Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation data are analyzed firstly and then
The distinctive feature of tidally locked exoplanets is the very uneven heating by stellar radiation between the dayside and nightside.Previous work has focused on the role of atmospheric heat transpo
The Yellow River loop valley (YRLV) is one of major agricultural production zones in many Chinese dynasties.Predicting rainfall variability in the YRLV is important for the society and the economy.
This study introduces a concept of global vs.local forecast skills of the Madden-Julian Oscillation (MJO).The global skill, measured by a commonly used MJO index (RMM), evaluates the models capability
由于臭氧,温室气体以及火山对平流层辐射和动力过程的作用,平流层温度监测变得极为重要,而卫星观测的出现使人们能获得全球平流层温度分析数据.本文利用卫星资料(Zou et al.2006,2009)来检验中国科学院大气物理研究所大气科学和地球流体力学国家重点实验室(LASG/IAP)发展的气候系统模式.
We aim to identify the multi-decadal variability (MDV) relative to the current centennial global warming trend in available observation data.The centennial global warming trend is first identified in
近十多年来全球增暖的停滞现象(warming hiatus)引起了气候内部变率和外部强迫相对重要性的争论.在报告中我将从一个新的视角,用两组长时间气候模拟揭示气候内部变率本身对外强迫引起的全球平均温度变化影响很小,但在区域尺度上气候内部变率和受迫变化之间可能存在不可忽视的相互作用.
本文就利用珠江三角洲1961-2010年23个代表站的逐日降水资料,基于空问标准化相对降水量,研究珠三角城市化进程不同阶段的强降水空间分布变化.结果表明,伴随珠江三角洲城市化进程的显著加快,全年强降雨量、强降雨的强度、强降雨日数呈现出明显的城市雨岛分布特征.
