Association between earthquake and equatorial waves in outgoing longwave radiation over South East Asia

Lal, M.; Bhagavathiammal, G.J. (2016)

In the present study, efforts have been made to correlate the equatorial waves in outgoing longwave radiation (OLR) and seismic activities in South East Asian region. The OLR data has been obtained from NOAA Climate ...
Geomagnetic-induced tropopause temperature and wind variation over low latitude

Lal, M.; Subramanian, M.V. (2008)

The present study reports the effect of geomagnetic storm on 200 mb altitude temperature and wind at a low latitude (8.7°N, 77.8°N) Indian region. The severe and strong geomagnetic storm (Dst < – 100 nT) between 2000 and ...
Meteorological characteristics changes in equatorial latitude associated with solar activity

Lal, M.; Subramanian, M.V. (2007)

We have made an attempt to study the influence of geomagnetic storm on the equatorial upper troposphere temperature and wind variability. The NCEP — Re analysis data has been taken as an input for the present study. The ...
A Model study of the atmospheric heating rates due to O3, H2O and O2

Lal, M. (2001)

The height distribution of solar heating rate due to ozone, water vapour and oxygen molecule from ground to 100 km altitude has been examined in this study. The cooling rate due to infrared emission of CO2, O3 and water ...
A modeling study of the nighttime equatorial E region behavior during magnetospheric substorms and storms

Kim, V.P.; Hegai, V.V.; Lal, M. (2002)

[1] The results of a modeling study of the variations of altitude ion density distribution in the nighttime E region over the magnetic equator during strong magnetospheric substorms and storms due to perturbations of the ...
A relation between cosmic rays and Dst field

Lal, M.; Srivastava, Pankaj K. (2001)
Stability analysis of the Gravito-Electrostatic Sheath-based solar plasma equilibrium

Karmakar, P.K.; Goutam, H.P.; Lal, M.; Dwivedi, C.B. (2016)

We present approximate solutions of non-local linear perturbational analysis for dis- cussing the stability properties of the Gravito-Electrostatic Sheath (GES)-based solar plasma equilibrium, which is indeed non-uniform ...
Study of ozone variability at equatorial latitude during severe geomagnetic storm

Lal, M. (2007)

We have studied the influence of geomagnetic storms on the total ozone variability over equatorial and polar latitude region. Total Ozone Mapping Spectrometer (TOMS) and METEOR- 3 satellite have provided the long duration ...
