The Gravity Waves and its Implication on Atmosphere

As a result of destabilizing processes Gravity waves are formed in the atmosphere. Gravitational-wave astronomy is a branch of astronomy which uses gravitational waves to collect observational data about sources of detectable gravitational waves. Whenever a destabilizing incidence happens in the atmosphere such as, weather fronts, during storms or when air masses struck over mountain ranges the Gravity waves are created. They reflect in the sky in the form of the bands of cloud. They cannot be used for weather forecast due to their shorter wavelength of few hundred metres and several hundred kilometres; however, they can strongly influence the transport of water vapour as well as large-scale winds and temperature distributions to a large extent. Those Gravity waves also play an important role in predicting air traffic turbulence and are estimating weather extremes, like heavy rain or storms. Research has been done to describe the influence of gravity waves, in weather and climate models with typically coarser resolution. A new model named UA-ICON, has been developed that allows more accurate predictions for the upper atmosphere and can be operated with different resolutions, so that gravity waves can either be simulated in it for test purposes or must be adjusted in the operational form. This new project will also focus on impacts on weather prediction and climate modelling for better as well as accurate understanding and predictions.
