Amazon Hydrological Cycle: Past, Present, Future As an enthusiastic Climate Modeller, you will be working on a project aiming to improve our understanding of the past and current variability of the hydrological cycle of the Amazon basin. The Amazon basin is a major centre for atmospheric convection, and thus changes in the hydrology of the basin as a result of climate change, or changes in vegetation cover, may influence climate globally. Existing records of the Amazon hydrological cycle (river discharge and precipitation) reveal that the Amazon is experiencing a substantial intensification. In this project we aim to better understand this recent trend by collecting new tree ring and water isotope data from the Amazon basin. We will analyse these and already existing records using an isotope enabled coupled climate land vegetation model as well as a back-trajectory based approach, developed by members of our team. A main goal of the project is to understand an existing d18O tree ring record from Bolivia spanning the last 100 years, as well as new records to be obtained based on the same methodology at several other sites along the main air path over the Amazon. Besides tree ring records we will also collect precipitation d18O samples at three places as well as riverine d18O. Additional records include those from ice-cores. One of our aims is to increase our understanding of recent trends in the Amazon hydrological cycle revealed by river and precipitation records. We also aim to disentangle the role played by recirculation of water to the atmosphere by land vegetation, as opposed to water precipitated from incoming moist air. You will have good mathematical skills and be familiar with running large geophysical fluid dynamics codes. Ideally, you will have familiarity with running climate models. You will be interested in a systems and big picture view of the coupled land vegetation climate system. Additionally, you will have a PhD in the field of environmental sciences, geophysical fluid dynamics or similar and a background in quantitative sciences. Fixed term for 36 months. University Grade 7 (£30,728 - £36,661 p.a.) Informal enquiries may be made to Professor Emanuel Gloor, tel +44 (0)113 343 3305, email firstname.lastname@example.org. Closing Date: 3 February 2014 More details can be found at: http://jobs.leeds.ac.uk/fe/tpl_universityofleeds01.asp?s=4A515F4E5A565B1A&jobid=108704,8287783621&key=8582180&c=788799484159&pagestamp=sealokvlewvkrohvli
