Research Interests
Discrete propagation of convection

Continuous propagation describes the generation of new cells at the edge of the gust front.  Discrete propagation refers to cell initiation that, while not generated at the outflow edge, is significantly influenced by nearby or previous convection (e.g. gravity waves propagating beyond gust front or fossilized cold pools).

Does the transport of surface radon affect lightning initiation? I have some runs that show mid-tropospheric radon concentrations are sufficiently increased in vigorous storms such that radon may provide a quantity of seed electrons to rival the quantity available from cosmic rays. If you are interested in this topic, please contact me. This is a project I may not have time to complete myself; I welcome collaborators. Also, please contact me if you could recommend a better radon map ( this map is for indoor radon concentrations only.)
