Kinetic energy budgets of an extratropical cyclone and Hurricane Celia, 1970 are examined in moving coordinates. This represents a first attempt to diagnose the energy budgets of moving systems using the method suggested by Vincent & Chang (1973).Both systems are studied during three stages of ...
Predictability of a Mediterranean Tropical-Like Storm Downstream of the Extratropical Transition of Hurricane Helene (2006). The extratropical transition (ET) of a tropical cyclone is known as a source of forecast uncertainty that can propagate far downstream. The present study f... Pantillon,Florian...
However, no tropical cyclone warning center currently performs a rigorous verification of ET forecasts. This paper presents result from an experimental verification of ET forecasts at the National Hurricane Center from 1996-2007. The verification has two parts. The first is a version of the 2 x...
As a tropical cyclone (TC) undergoes recurvature, its diabatically driven divergent outflow may interact with the extratropical flow such that a jet streak develops and/or an upper-level ridge amplifies. In some instances, the TCextratropical flow interaction can excite or amplify a Rossby wave ...
Tropical cyclones (TCs) that move polewards and recurve may transform into an extratropical cyclone and interact with the midlatitude flow. This interaction can result in a modification of the upper-level midlatitude Rossby wave guide and thus has implications for the weather and predictability in ...
