research on the diffusion characteristics of swells contributes positively to wave energy forecasting, swell monitoring, and early warning. In this work, the south Indian Ocean westerly index(sIWI) and Indian Ocean swell diffusion effect index(IOsDEI) are defined on the basis of the 45-year(september 1957–August 2002) ERA-40 wave reanalysis data from the European Centre for Medium-Range Weather Forecasts(ECMWF) to analyze the impact of the south Indian Ocean westerlies on the propagation of swell acreage. The following results were obtained: 1) The south Indian Ocean swell mainly propagates from southwest to northeast. The swell also spreads to the Arabian sea upon reaching low-latitude waters. The 2.0-meter contour of the swell can reach northward to sri Lankan waters. 2) The size of the IOsDEI is determined by the sIWI strength. The IOsDEI requires approximately 2–3.5 days to fully respond to the sIWI. The correlations between sIWI and IOsDEI show obvious seasonal differences, with the highest correlations found in December–January–February(DJF) and the lowest correlations observed in June–July–August(JJA). 3) The sIWI and IOsDEI have a common period of approximately 1 week in JJA and DJF. The sIWI leads by approximately 2–3 days in this common period.

Buitrago and colleagu.s.should be commended on an excellent case report on the effective use of the robotic platform for a successful minimally invasive left lower lobectomy for a patient with biopsy proven squamous cell carcinoma.1 Despite a predicted postoperative forced expiratory volume in one second(ppoFEV1)of 23%and a preoperative diffusing capacity for carbon monoxide(DLCO)of 21%,the patient underwent a lobectomy without any intraoperative complications or evidence of disease at 15 months *** node sampling was performed from 5 *** postoperative length of staywas not clearly *** authors made several interesting points about the impact of pulmonary function on postoperative outcomes,the oncological efficacy of lobectomy versus sublobar resections,and merits of roboticassisted thoracoscopic surgery(RATs)versus thoracotomy and conventional video-assisted thoracoscopic surgery(VATs).We would like to discu.s.these points in further detail based on the available evidence in the current literature.

The G-WADI network by uNEsCO promotes the global capacity for management of water resources in arid and semi-arid areas. The primary aim has been to build a comprehensive global network to promote regional and international cooperation so as to in- crease knowledge and improve management practices through the sharing of information. The G-WADI objectives and achieve- ments of the past 10 years are reviewed. A number of key initiatives have been implemented^the formation of five regional net- works, the creation of a central G-WADI web site, promotion of near-real-time rainfall distribution software enhanced by the in- clusion of satellite based precipitation estimations, as well as workshop and web-based activities on chemical and isotopic tracers and on rain water harvesting. Two workshops on surface and on groundwater modeling, supported by publications have been held in India and China. The Asian G-WADI network remains very active, but activities in the other three regions are developing （Af- rica, Arab Region, Latin America and the Caribbean）.

Further study of Typhoon Tracks and the Low-Frequency (30-60 Days) Wind-Field Pattern at 850 hPa

Atmospheric and Oceanic science Letters 2010年第6期3卷 319-324页

作者： TIAN Hua LI Chong-Yin state Key Laboratory of Numerical Modeling for Atmospheric sciences and Geophysical FluidDynamics （LAsG） Institute of Atmospheric Physics Chinese Academy of Sciences Beijing 100029 China Editorial Board of the institute of Atmospheric Physics Beijing 100029 China institute of Meteorology the People＇s Liberation Army （PLA） University of Science and Technology Nanjing 211101 China

The association of typhoon tracks over the western Pacific with the low-frequency wind-field pattern of atmospheric intraseasonal (30-60 days) oscillation at 850 hPa is further studied by using observational data analyses. Comparative analyses of the composite wind fields at 850 hPa, contrasting the atmospheric intraseasonal oscillation (IsO) with the original circulation, show that the typhoon tracks are closely related to the wind pattern of the IsO but are not obviously related to the original wind fields. Case studies of two typhoons in 2006 also show that the low-frequency wind-field pattern, particularly the maximum-value line (belt) of low-frequency cyclonic vorticity at 850 hPa, is closely related to the typhoon track. Therefore, the lowfrequency circulation pattern and the maximum-value line (belt) of low- frequency cyclonic vorticity at 850hPa can be used to predict typhoon tracks over the northwestern Pacific.
