Kim et al. (2013) - WRF (0.36 deg, nested domain 0.09deg; over 10 years):
1) interannual variations relatively good
2) Freezing level anomalies with ARs good
, (Global impacts
-AR landfalls are most frequent in west coast of U.S.;
But, notable in many other areas too.
(Waliser et al. 2012)
), Known-causes of ARs from a small scale to a large scale (AO [Arctic Oscillation], ENSO [El Niño Southern Oscillation], MJO [Madden-Julian Oscillation] etc) - negative AT and negative PNA (Pacific/North American teleconnection pattern) tend to be assocaited with more stormy weather in California. - When the AO and PNA are both in the negative phase, ARs are significantly more likely to occur.
, Future projection of AR as climate changes (temperature increase, drought) - more atmospheric vapor content - weakening westerly winds -increase of intensity of AR storms - warmer ARs - lengthening of AR seasons? Dettinger, M.D., 2011,
