The Low Pressure Systems (LPS) are atmospheric vortices of varying intensity embedded in the large scale monsoon circulation. Although the LPS are found in almost all monsoon regions around the world, they are most prominent over the Bay of Bengal (BoB) and adjoining Indian continent during boreal summer. As many as 12 LPS form over Indian region during a typical summer monsoon season. Most of these systems form over the BoB and follow a northwest track across the Gangetic plains, producing large amount of rainfall all along their trajectories. In fact, more than half of the rainfall received over the central India is contributed by these storms. Thus LPS are an important component of the regional hydrologic cycle. The project proposes to examine the LPS activity in IITM Global Forecast System (GFS) model's short range and extended range hindcast simulations.
