Data & Tools
Real-time operational forecasts of South Asian monsoon depressions:
Global track datasets of monsoon disturbances:
- Tracks in 5 atmospheric reanalyses compiled using an optimized algorithm, as described in Vishnu et al. (2020). That archive only extends through 2019; ERA5 tracks for 1940–2022 are available here.
- Older dataset based on ERA-Interim data for 1979–2012, 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 Asia. 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.
