Based on observational data and Asian monsoon intensity datasets from China, the relationships between the East Asian winter monsoon index and winter temperature, the East Asian summer monsoon index and Meiyu precipitation over the middle and lower reaches of the Yangtze River, were analyzed. We found that the monsoon signals were reflected in the temperature and Meiyu precipitation variations....

The interannual variability of monsoon precipitation is described in the context of a convective quasiequilibrium framework. Using two reanalysis products and two global precipitation datasets, the authors examine linear relationships between seasonal anomalies of precipitation and subcloud equivalent potential temperature (ueb) local to six monsoon regions. This approach provides a single near...

[1] Understanding the origin and perpetuation of the monsoon cycle has eluded scientists for decades. Using a suite of unprecedented satellite measurements, we show that the antecedents of the active/break monsoon emerge in the western equatorial Indian Ocean (EIO). The initiation of a new rainy phase in the western EIO is preceded by in situ surface wind convergence and central EIO warming, bo...

Elevated heating by the Tibetan Plateau was long thought to drive the South Asian summer monsoon, but recent work showed this monsoon was largely unaffected by removal of the plateau in a climate model, provided the narrow orography of adjacent mountain ranges was preserved. There is debate about whether those mountain ranges generate a strong monsoon by insulating the thermal maximum from cold...

The Asian summer monsoon affects more than sixty percent of the world's population; understanding its controlling factors is becoming increasingly important due to the expanding human influence on the environment and climate and the need to adapt to global climate change. Various mechanisms have been suggested; however, an overarching paradigm delineating the dominant factors for its generation...

Myanmar and Thailand often experience severe droughts and floods that cause irreparable damage to the socio-economy condition of both countries. In this study, the Southeastern Asian Summer Monsoon variation is found to be the main element of interannual precipitation variation of the region, more than the El Niño/Southern Oscillation (ENSO). The ENSO influence is evident only during the boreal...

Analysis of the 140-year historical record suggests that the inverse relationship between the El Nino-Southern Oscillation (ENSO) and the Indian summer monsoon (weak monsoon arising from warm ENSO event) has broken down in recent decades. Two possible reasons emerge from the analyses. A southeastward shift in the Walker circulation anomalies associated with ENSO events may lead to a reduced sub...

calanoid, cyclopoid, harpacticoid and poecilostomatoid copepods were investigated over the year at five stations in the chabahar bay, oman sea. this area is under the influence of the indian ocean seasonal monsoons. the samples were collected using vertical plankton tows with 100 µm mesh nets. copepods were identified into 20 genera and 59 species. calanoid formed about 15% to 62% and cyclopoid...

in the current attempt, the relation between precipitation change in southern coasts of iran and sea level pressure data of ncep / ncar database were investigated through correlation method using environment to circulation approach in the period of 1960-2004. after calculating the correlation matrix between the percipitation amount and pressure, the precipitation-pressure correlation map for ea...
