Part 2 Flashcards
ADT algorithm is strongly dependent on…..
Scene type, with best performance for scenes when a clear eye is present and decreased algorithm performance for other scene
Air parcels over wpo flow
Eastward aloft
Why do eyewalls slope outward with increasing height
Warm core structure and thermal wind balance
Non tropical low and thunderstorm complexes
Associated with regions of strong upper-level divergence causes surface pressures fulls and generation of deep convection frequent precursor of subtropical cyclones
Mass convergence over the pole, along with cooling through the column
Produces subsidence and surface nigh pressure over the pole
Low - level mass diverging outward at the surface from the pole flow toarf
Low pressure at the equator where it converges rises and completes the Hadley cell.
Polar -orbiting sat disadvantages
Cannot see whole earth’s surface at once path changes so no image same 6-7 images a day
Geostationary sat disadvantages
High altitude provides lower detail polar regions limited due to curvature
Validation consist of…..
Warning agency best track estimates of vmax and mslp during periods when aircraft ground truth was available within three hours of intensity estimate
June storms
1 on average typically occurs in nw Caribbean or Gom
Upper - level mass diverging outward aloft from the equator creates
Low pressure at the surface at the equator
Tropical cyclones and tropical waves are
Temporally synoptic - scale weather systems
Satcom error
9 knots
Ckz
Pressure-wind relation ship which incorporates latitude size, storm motion and environmental pressure
Rainfall
Forward speed size topography mountains fronts upper-level troughs
