The response of glaciers to changing climate is explored with an atmosphere/glacier hierarchical modeling approach, in which global simulations are downscaled with an Arctic MM5 regional model which provides temperature and precipitation inputs to a glacier mass-balance model. Themass balances of Hubbard and Bering Glaciers, south-central Alaska, USA, are simulated for October 1994–September 20...
Under the 11th Five Year Plan (FYP, 2006e2010) for national environmental protection by the Chinese government, the overarching goal for sulfur dioxide (SO2) controls is to achieve a total national emissions level of SO2 in 2010 10% lower than the level in 2005. A similar nitrogen oxides (NOx) emissions control plan is currently under development and could be enforced during the 12th FYP (2011e...
The anti-tumour activity of the Au (I) phosphine complex [Au(dppe(2)]Cl was first discovered in the mid 1980s although promising results were obtained it did not pass clinical studies because of its toxicity to organs such as the liver and heart. The aim of this study was to determine whether the two novel gold compounds (MM5 and MM6), selected for this study, have higher selectivity for cancer...
A method based on a statistical approach of estimating uncertainty in simulating the transport and dispersion of atmospheric pollutants is developed using observations and modeling results from a tracer experiment in the complex terrain of the southwestern USA. The method takes into account the compensating nature of the error components by representing all terms, except dispersion error and va...
A surface-precipitation-rate retrieval algorithm for 13-channel Advanced Microwave Sounding Unit (AMSU) millimeter-wave spectral observations from 23 to 191 GHz is described. It was trained using cloudresolving fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) simulations over 106 global storms. The resulting retrievals from the U.S. N...
پدیده نسیم دریا- خشکی یکی از مشخصههای مهم مناطق ساحلی در طول ماههای گرم سال است که تاثیر قابل ملاحظهای در آب و هوا، و همچنین پخش و پراکندگی آلایندهها در مناطق ساحلی دارد. آگاهی صحیح از چگونگی شکلگیری نسیم دریا- خشکی، خصوصیات، و نهایتا میزان تاثیرات آن در مناطق ساحلی میتواند پیامدهای مهمی برای عموم ساحل نشینان و دریانوردان، داشته باشد. در این پایان نامه بعد از معرفی این پدیده، اثرات و راه...
