Call for Papers - IJRSP Special Issue

Middle Atmospheric Dynamics and Coupling in the Tropics

The middle atmosphere is traditionally considered to extend from the tropopause (~15 km in the tropics) to the mesopause (~100 km). Tropical regions are characterized by intense convection that is known to generate a spectrum of atmospheric gravity waves. The tropical tropopause region is highly variable and controls the transport of minor constituents like water vapor and ozone. The latitudinal variation of the Coriolis frequency at low latitudes is such that certain long-period (of a few days) eastward propagating waves are trapped in the middle atmospheric region there. Tides and planetary waves along with these equatorially trapped waves play an important role in the momentum budget of the middle atmosphere. The short-period gravity waves also carry significant energy and momentum upwards and are able to propagate to great heights into the upper atmosphere.

There has been considerable interest in a number of topics of relevance to middle atmospheric dynamics and coupling at low latitudes in recent years and significant advances have been made in some of these topics. To consolidate those studies, we had proposed to bring out a special issue of Indian Journal of Radio & Space Physics (IJRSP). Papers dealing with observations, theory and modeling of the topics listed below are solicited for the special issue.

Topics of interest to the special issue Stratosphere-Troposphere exchange processes: role of tropopuse dynamics and temperatures - dynamical efffects on transport of minor constituents like water vapor, ozone, etc.Role of clouds and deep tropical convection in the generation of mesoscale waves, planetary waves and locally generated gravity wavesMechanisms for the generation of middle atmospheric gravity wavesOscillations in middle atmospheric winds with different periods including QBO and SAO and their effects on planetary wave propagation in the mesosphere-lower thermosphere (MLT) region, the tropical easterly jet, Asian monsoon and El Nino phenomenonEquatorial waves in the Indian tropical middle atmosphere - generation and propagation characteristics - contribution to QBO and SAO momentum budgetsLinkage between tropical cyclone over Indian seas and stratospheric and mesospheric temperatures - do the middle atmospheric temperatures have the forecasting potential to predict cyclones?Stratwarm events, their associated circulation changes and their effects on energetics of the tropical lower and middle atmosphereGravity wave activity at mesopause heights: spatial and temporal variabilitiesDynamical links of MLT region to the tropical tropospheric variabilityNon-migrating tides: generation and characteristicsImportant Notes
