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

Global track datasets of monsoon disturbances:

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.

Output from an idealized quasi-global aquaplanet model run without a convective parameterization (through use of the hypohydrostatic rescaling), from our paper that used this model to study the response of extreme precipitation to uniform surface warming.

Moist energy balance model, written in Python by Henry Peterson and used in Peterson and Boos (2020) to analyze the influence of radiative feedbacks and eddy diffusivity on tropical rainfall shifts.


My research group has an opening for a new graduate student to start in Fall 2021. Details can be found here.
