Some analysis of 2010 Christmas East Coast Storm
Yucheng Song
Dec 24,06Z f06 minus Dec 24, 12Z dry energy norm for 850,500 and 200mb
Quite interesting, who has caused the increase there?
Dec 24,06Z f06 minus Dec 24, 12Z 500mb height and wind
These two areas are spotted
Points: if certain phenomenon can’t be resolved by the model physics, then observations at a later time have to be relied up on
Sensitivity calculation
One uncertainty areaNear Texas/MexicoSpotted by ET KF
Initialized on Dec 23,00Z
Propagating
From Richard GrummThis shows the how the error grows with time
If we had a mission on Dec 23/12Z, it would help
The little blob near Texas grows rapidly
Sparse observing network in the South/Mexico
