Evaluation of the performance of the CMIP5 General Circulation Models in predicting the Indian Ocean Monsoon precipitation over south Sistan and Baluchestan, using the past hydrological changes in the region
1-Introduction Climate change refers to any significant change in the existing mean climatic conditions within a certain time period (Jana and Majumder, 2010; Giorgi, 2006). Earth's climate change through history has happened (Nakicenovic et al., 2000; Bytnerowicz et al., 2007). 2-Materials and methods In this study, daily precipitation and daily maximum (Tmax) and daily minimum (Tmin) tempera...
متن کاملThe relative roles of upper and lower tropospheric thermal contrasts and tropical influences in driving Asian summer monsoons
[1] Summer thermal structure and winds over Asia show a larger land-ocean thermal gradient in the upper than in the lower troposphere, implying a bigger role of the upper troposphere in driving the Asian summer monsoon circulation. Using data from atmospheric re-analyses and model simulations, we show that the land-ocean thermal contrast in the mid-upper (200–500 hPa) troposphere (TCupper) cont...
متن کاملChanging links between South Asian summer monsoon circulation and tropospheric land-sea thermal contrasts under a warming scenario
[1] Forced with increased greenhouse gases, the South Asian summer monsoon (SASM) circulation weakens in climate models, which appears inconsistent with the projected increases in near-surface land-sea thermal contrasts during the 21st century. Our analysis shows that the SASM intensity positively correlates with the land-sea thermal contrast in both the lowerand upper-troposphere before year 2...
متن کاملResponses of East Asian summer monsoon to historical SST and atmospheric forcing during 1950–2000
The East Asian summer monsoon (EASM) circulation and summer rainfall over East China have experienced large decadal changes during the latter half of the 20th century. To investigate the potential causes behind these changes, a series of simulations using the national center for atmospheric research (NCAR) community atmospheric model version 3 (CAM3) and the geophysical fluid dynamics laborator...
متن کاملGlobal Monsoon in a Changing Climate
Monsoons, the most energetic tropical climate system, exert a great social and economic impact upon billions of people around the world. This chapter reviews recent progress in our understanding of the global monsoon (GM) system and its associated precipitation changes in the present and future warming climates. The GM can be viewed as an integrated system of all regional monsoons over the glob...
