Research interests and themes
My career began with studies of atmospheric convective clouds and
storms, initially in field observations (fun campaigns!). But the
larger context of tropical weather and climate must always be
appreciated, or else storm meteorology is just stamp collecting.
That larger picture requires understanding other processes like
radiation, surface effects, mixing, and of course dynamics:
the mathematical glue of differential equations that connects all
these parts. Working with postdocs, students, and collaborators, I
try to maintain a 3-pronged effort that builds from local scales
(very definite and tangible, but always dependent on what lies
beyond), through quantitative analysis and abstraction, up toward
global scales (vast and pervasive, yet evasive: the average is
everywhere and nowhere).
1. We study convective
the vertical) , using observations (radars, aircraft,
soundings, satellites) and cloud-resolving models.
2. We study the large-scale
net thermodynamic and dynamic effects of convection and
related processes in the atmosphere, guided by observations; and
then try to encapsulate the essence in simple models (the
3. We study several
large-scale weather and climate phenomena using regional and
global observations and models, to lend more context and meaning to
the activities described above.
