Does sudden stratospheric warming induce meridional circulation in the mesosphere thermosphere system?

Laskar, Fazlul I.; Pallamraju, Duggirala (Wiley, 2014-12)

Oxygen dayglow emissions at multiple wavelengths that emanate from different heights (from around 130 km to peak altitude of the ionospheric F region) over a low-latitude location showed systematic enhancements in intensities ...
Gravity waves in the thermosphere: solar activity dependence

Laskar, Fazlul I.; Pallamraju, Duggirala; Veenadhari, Bhaskara; Vijayalakshmi, Tatiparti; Reddy, M. Anji; Chakrabarti, Supriya (Elsevier, 2015-03)

A statistical study of the thermospheric gravity waves has been carried out using multiwavelength daytime oxygen airglow emission intensity and equatorial electrojet (EEJ) strength data, which originate from four different ...
Vertical coupling of atmospheres: dependence on strength of sudden stratospheric warming and solar activity

Laskar, Fazlul I.; Pallamraju, Duggirala; Veenadhari, Bhaskara (Terra Scientific Publishing Company, 2014-08)

Comprehensive behavior of the low-latitude upper atmosphere during sudden stratospheric warming (SSW) events at varying levels of solar activity has been investigated. The equatorial electrojet (EEJ) strength and the total ...
