GLASH images readily illustrate features from planetary waves, to synoptic scale frontal features, to mesoscale features, and even, ultimately, finely-scaled evidence of irreversible mixing.
Key Features
 |
Strong gradients in the derived brightness temperature of GLASH imagery correspond to the boundaries of well defined airmasses, like the boundary between dry polar stratospheric air and moist subtropical tropospheric air. |
|
The dynamical tracer of isentropic potential vorticity provides a model-derived quantity based on wind fields and thermodynamic profiles, and it corresponds very well with the GLASH image, demonstrating the dynamical tracer value of the GLASH product. |
