Research interests and themes
My work began with studies of atmospheric convective clouds and
storms. But the larger context of tropical weather and climate must
always be admitted, 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 glue that connects all these parts. Working with
postdocs, students, and collaborators, I maintain a 3-pronged effort
that builds from local scales (very definite and tangible, but
always dependent on what lies beyond), via quantitative analysis and
abstraction, up toward global scales (vast and pervasive yet
evasive: everywhere and nowhere).

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
