Info

TC Relocation• Based on the assumption that modelsimulated vortex has reasonable structure• The model vortex is lifted from a previousforecast, and moved to the current, correctlocation• Works better on pressure level data• May adjust vortex profile after relocation• Papers by Liu et al. (1997), Tenerelli et al.(2001)Mesoscale & Microscale Meteorological Division / NCAR 10
Pros and Cons• Advantage:o Easy to implement, especially with moving nest• Disadvantage:ooBlending of vortex environment may beproblematicMay have problem with storm relocating fromocean to land or vice versa• Tools available to do this:o p_interp: put model data on pressure levelsMesoscale & Microscale Meteorological Division / NCAR 11
