I’m thinking about my carbon footprint and trying to minimize travel, though I do undertake trips that are important for my mission of trying to improve the understanding and prediction of precipitation in tropical, developing countries. I post my travel plans here in hopes that future trips might be combined to minimize air travel. One cross-country, round-trip U.S. flight emits about 1000 kg of CO2, while one long-haul international round trip emits about 2000 kg of CO2. In comparison, all of the electricity, natural gas, and municipal water used by my 2-person household are estimated to generate about 4500 kg of CO2 per year.

Data & Tools, a website with educational pages and recent news about monsoons

Global track dataset of monsoon disturbances, as described in Hurley and Boos (2015)

Somali jet index, a measure of the strength of the South Asian monsoon circulation, and of roughly 30 percent of the global cross-equatorial flow

South Asian vertical shear index, the strength of the vertical shear of the zonal wind over South Asian. This was developed by Webster and Yang (1992, QJRMS) as a measure of the strength of the South Asian monsoon circulation.


I am pleased to announce a new, multi-institutional partnership to improve understanding and prediction of monsoon rainfall. As part of this new effort, my group is actively seeking two postdoctoral scientists and a software developer/programmer. We additionally expect to admit one or two new Ph.D. students to start in Fall 2019.
