Numerical simulation plays an increasingly important role in many scientific and engineering applications like climate modeling. One of the important problems in climate science is forecasting and tracking cyclones. Large-scale and long-range forecasting of cyclones involves high amount of parallel computations with large data sets, subsequent data analysis and high-resolution visualization for scientific discovery. In this work, we have developed an adaptive framework that performs simultaneous simulations and online visualization for forecasting and tracking cyclones. Our framework contains automatic mechanisms for identifying cyclones, adaptively changing the resolutions of forecasts and visualizations, the resource configurations for executions and the amount of data for visualization based on the cyclone characteristics. We have used our framework for tracking a tropical cyclone, Aila, in the Indian region.
