Climate and the Hydrological Cycle (MO408M) Bart van den Hurk (www.knmi.nl/~hurkvd) IMAU (Wednesday): B614 KNMI (other days): B3.36 [email protected] Aarnout van Delden (IMAU) Geert Jan Roelofs (IMAU) Material • Lecture notes – Land processes in climate models • Presentations • Articles • Accessible via blackboard and www.knmi.nl/~hurkvd Basic structure of course • 3 major topics – Land surface processes in the climate system • • • • how to parameterize climate zones Land use Land-atmosphere interaction – Dynamical meteorology • Water-related feedbacks • Zonal structure and PV • Diagnosing diabatic processes from PV – Clouds and aerosols • Cloud microphysics • Clouds, aerosol and climate • Isotopes and the hydrological cycle Course aims • • • • • • • • • • • • ability to describe and basically understand the seasonal and interannual variability of the large scale circulation of the atmosphere and the associated transport of water vapour. ability to describe and basically understand how atmospheric radiative processes, the energetics of the water cycle and large scale planetary waves determine the seasonal cycle of temperature and wind-jets. understand the physical (radiative and thermodynamic) aspects of aerosol, clouds and land surface processes acquire knowledge on microphysical and chemical properties of aerosol and clouds, and understand their role in aerosol direct and indirect climate effects understand the physical principles of processes, interactions and feedbacks at the land surface – climate interface have an overview of key diagnostics of land-atmosphere interaction demonstrate a broad insight in how the different aspects of the hydrological cycle are related and interact understand how the hydrological cycle affects and is affected by climate and climate change having explored and understand scientific literature on a subject associated with aerosol, clouds, water cycle, land surface processes and climate understand and manipulate a conceptual model of land-atmosphere interaction technically process records of observations and model output of land surface variables formulate a simple hypothesis related to land surface processes, evaluate observations and/or model output relevant for this hypothesis, and report on the results and conclusions from this evaluation. Examination Three projects (each 30%) – Conceptual land-atm interaction model – Exploring ERA-interim – Essay on clouds/aerosols One presentation on either topic (10%) Presentation + 3 project reports are evaluated one final grade • • • • • • • • • • • • • • • • • • • • • Schedule 6: introduction land and dynamics Bart van den Hurk 7: introduction clouds Aarnout van Delden 8: land parameterization Geert Jan Roelofs 9: land use change 10: land-atmosphere interaction 11: no lecture 12: land-atmosphere interaction + introduction to land exercise 13: intrduction dynamics and water-related feedbacks 14: zonal characteristics and potential vorticity 15: zonal characteristics and potential vorticity 16: deadline essay on land exercise 17: interaction dynamics/water/radiation 18: presentations land exercise 19: interaction dynamics/water/radiation 20: cloud microphysics 21: cloud microphysics 22: aerosols, clouds and climate 23: aerosol chemistry 24: presentation dyn exercise 25: isotopes and hydrological cycle 26: presentation cloud exercise Evaluation criteria • Main criterion is the physical rationale of the essay – Is it well structured (intro, questions, material, results, conclusions) – Is the physical hypothesis well related to the analysis? • Marks – 10: publishable – 9: innovative – 8: good set-up and rationale, no inconsistencies – 7: fair set-up and rationale – 6: data are used and described but clarity is limited – 5: analysis not compatible with hypothesis – 4: physical inconsistencies • Secondary criteria are used for round-off (language, references, readability, clarity of figures) Registration • Please register at – Bureau Onderwijs Zaken (BOZ), Minnaertbuilding Rm 119 – Also non-MSc, non-Utrecht participants!
