Part 5 Flashcards
ADT frequently misplaces low-level by more than - nmi
30
ADT utilizes an
Objective storm center determination scheme and cloud pattern determination logic to remove subjectivity
Wind profilers
Measures and displays wind info up to 16 km can detect low level wind shear
Global upper-air network - to accurately determine the intensity of tropical cyclones
Is not sufficient
(Old over shooting convective clouds develop along the
Radius of max winds
July storms
1-2 western Atlantic Caribbean Gom
What strengthens the pacific easterly trade winds
East-to-west orientated pressure gradient between the E PO and wpo
The - the - and the - the - the more -a hurricane can become
Colder; out flow temperature; warmer; surface inflow temperature; intense
Ferret cell is -
Thermally indirect
Pressure underneath the eyewall is - than the pressure is in the eye
Locally lower causes air to flow out of the eye and into the eyewall
Aidt rms error
8kt
24-hr total rainfall =
100/ storm motion
Guan stations are set at -
5 to 10 degrees of latitude, sufficient to resolve synoptic-scale waves
What is given in an ADT intensity
Only the storm Id not the name
Ccc
Central cloud cover - large cold dense over cast covering the Csc that lacks structure and obscures center
Aircraft collect high-density observation data
30 sec average 10 sec average peak during 30 sec interval 10 sec average peak sfmr derived surface wind speed 10 sec smfr derived ran rate heavy rain can inflate wind speed data quality control flags
ADT
Does not require direct input, completely objective
ADT, satcon,aidt satellite intensity bias
High bias above 120 knots and low below 60 knots
The Ethiopian disturbances typically move
Westward at 15 - 18 knots
Tropical cyclones often times - after passing over - water in the wake of a previous storm
Weaken, up welled
