Further investigation on stratospheric air intrusion into the troposphere during the episode of tropical cyclone: Numerical simulation and MST radar observations
چکیده انگلیسی

For the first time, spatiotemporal structure of stratospheric air intrusion into the troposphere during the episode of tropical cyclone is simulated using Advanced Research-Weather Research and Forecast (WRF-ARW) model. The WRF-ARW simulation effectively reproduces the spatiotemporal evolution of vertical velocity associated with tropical cyclone and shows good agreement with the mesosphere–stratosphere–troposphere (MST) radar observations at Gadanki (13.5°N, 79.2°E). The observed intrusion in the upper-troposphere has a narrow band with the width of about 50 km and stretch over 200–250 km and vertical structure of 5–6 km. This study shows that the intrusion occurs in the periphery of the cyclone and confirms that mesoscale simulation using WRF model can be used during disturbed weather conditions and for studying TSE processes.

Research highlights
► For the first time stratospheric intrusion is examined using WRF simulation.
► WRF simulation during the cyclone is well compared with MST radar observations.
► Impact of tropical cyclone on stratosphere–troposphere exchange processes
