July droughts over Homogeneous Indian Monsoon region and Indian Ocean dipole during El Niño events
The monthly summer monsoon rainfall over the Homogeneous Indian Monsoon region (HI) that represents most of the variance of all-India monsoon rainfall is investigated using observational data from 1880 to 2002. Severe droughts in July occur mostly during El Niño events of the boreal summer monsoon season. They occurred frequently in the late 19th to early 20th century, rarely in the middle of t...
متن کاملImpact of Indian Ocean Dipole on high-frequency atmospheric variability over the Indian Ocean
Article history: Received 14 March 2008 Received in revised form 24 July 2008 Accepted 14 October 2008 A strong relationship between Indian Ocean Dipole (IOD) and high-frequency (HF) atmospheric variability in the low-level zonal wind is reported in the present study. We found that the HF atmospheric variability over the Indian Ocean (IO) is strongly modulated by IOD events, that is, HF atmosph...
متن کاملSwell Propagation and Nearshore Wave Climate
Considerable coastal infrastructure has been developed in Chile over the last two decades, and the impetus for this study was based on concerns with the lack of consistency utilized in the coastal engineering design process, beginning with, but not limited to, the definition of the wave conditions. The available wave records in Chile are of very limited duration, thus many designers rely on a v...
متن کاملSemiannual Cycle in Zonal Wind over the Equatorial Indian Ocean
The semiannual cycle in zonal wind over the equatorial Indian Ocean is investigated by use of ocean– atmospheric reanalyses, and linear ocean–atmospheric models. In observations, the semiannual cycle in zonal wind is dominant on the equator and confined in the planetary boundary layer (PBL). Results from a momentum budget analysis show that momentum advection generated by the cross-equatorial m...
متن کاملOn the origin of tropospheric O3 over the Indian Ocean
A comparison and analysis of modeled and measured O 3 profiles from the INDOEX campaign is presented. European Centre for Medium-Range Weather Forecast (ECMWF) meteorological analyses have been assimilated into the model to represent actual meteorology. The focus of this study is on two commonly observed features 5 in the O 3 profiles: mid tropospheric O 3 maxima (300–500 hPa) over the tropical...
