Re: Earl and dry air

Just a passive observer of the site. It seems to only be briefly mentioned, but it seems clear to me that Earl has been drawing Fiona into itself over the past day. I know in the past, this has happened (I believe it was the 95 season I saw it happen, might of been Karen), though rarely, that the stronger storm swallows the weaker storm. I believe it also effects the stronger storm during this process. Can anyone give some clarity to what the effects on Earl will be during this process? How long this might take and do the models have this predicted in already?

Thanks

This is called the Fujiwara Effect
Considering NHC doesn't even mention Fiona in their discussion I think it's a good bet it won't be a major factor in steering for Earl.

THE SUBTROPICAL HIGH THAT IS
STEERING EARL TOWARD THE WEST-NORTHWEST OR NORTHWEST IS FORECAST TO
GRADUALLY SHIFT EASTWARD AS A BROAD TROUGH BECOMES ESTABLISHED OVER
THE EASTERN UNITED STATES. THIS PATTERN WILL FORCE EARL ON A MORE
NORTHWESTERLY AND NORTHERLY TRACK FOR THE NEXT DAY OR TWO.
THEREAFTER...EARL WILL REACH THE BASE OF THE MID-LATITUDE WESTERLIES
AND WILL LIKELY TURN SHARPLY TO THE NORTHEAST WITH AN INCREASE IN
FORWARD SPEED. THIS IS THE SOLUTION UNANIMOUSLY PROVIDED BY TRACK
GUIDANCE.
