A unified picture of plasma irregularities in equatorial spread F is developed from the
analysis of satellite, sounding rocket, and coherent scatter radar observations. The coherent …

The equatorial plasma bubble (EPB) phenomenon is an important component of space
weather as the ionospheric irregularities that develop within EPBs can have major …

We use radar observations from the Jicamarca Observatory from 1968 to 1992 to study the
effects of the F region vertical plasma drift velocity on the generation and evolution of …

This paper presents for the first time regional plots of total electron content (TEC) depletions
derived from GPS observations over the South American continent with a coverage of over …

Dynamic coupling of the atmospheric regions involving upward energy transport coupled
with the locally active thermal tidal modes establish the wind system of the thermosphere …

The Tonga volcano eruption of 15 January 2022 unleashed a variety of atmospheric
perturbations, coinciding with the recovery‐phase of a geomagnetic storm. The ensuing …

The daytime equatorial electrojet is a narrow band of enhanced eastward current flowing in
the 100–120 km altitude region within±2° latitude of the dip equator. A unique way of …

One of the oldest scientific topics in Equatorial Aeronomy is related to Spread-F. It includes
all our efforts to understand the physical mechanisms responsible for the existence of …

Magnetosphere–ionosphere coupling is responsible for storm time disturbance electric field
propagation to equatorial latitudes, by processes of direct penetration and disturbance wind …

A collisional shear instability in a magnetized plasma is described and evaluated. The
instability is related to electrostatic Kelvin Helmholtz but operates in inhomogeneous …
