The climatology of ionospheric plasma bubbles and irregularities over Brazil
In this paper, we examine ionospheric plasma depletions (or bubbles) and irregularities observed by photometers and a ground-based receiver of the global positioning system (GPS) both located in Brazil, South America. A simultaneous observation reveals that when the ionospheric plasma becomes depleted, the GPS total electron content decreases and the associated phase fluctuations grow. Statisti...
متن کاملA review on the numerical simulation of equatorial plasma bubbles toward scintillation evaluation and forecasting
Equatorial plasma bubbles (EPBs) have been a longstanding and increasingly important subject because they cause severe scintillations in radio waves from Global Navigation Satellite System satellites. The phenomenon was found in the 1930s as irregular ionosonde observations and was termed equatorial spread F (ESF). ESF is interpreted as plasma density irregularities associated with EPBs that ha...
متن کاملThe correlation of longitudinal/seasonal variations of evening equatorial pre-reversal drift and of plasma bubbles
The evening pre-reversal vertical drift velocity enhancement (PRE) constitutes an important seeding mechanism for the generation of F region irregularities. Ion density and drift measurements from ROCSAT-1 and DMSP satellites are used to examine the correlation of longitudinal/seasonal (l/s) variations in the evening pre-reversal vertical drift velocity at the magnetic equator in the topside io...
متن کاملQuasi-Analytic Models for Density Bubbles and Plasma Clouds in the Equatorial Ionosphere
The equatorial ionosphere contains imbedded bubbles that rise though a horizontally stratified plasma. The motion of the bubbles are affect by gravity, neutral winds or external electric fields which produce electric fields in the F-Region density perturbations of the bubbles. Exact solutions for the electric potentials are derived assuming linear or circular symmetry to the density structures ...
متن کاملSurface Heat Balance in the Equatorial Pacific Ocean: Climatology and the Warming Event of 1994–95
The surface heat budget in the equatorial Pacific Ocean was investigated through ocean model simulations, both the climatological cycle and the case of the 1994–95 warm event. The dominant processes governing the seasonal cycle of sea surface temperature (SST) vary significantly across the basin. In the western Pacific the annual cycle of SST is primarily in response to net surface heat flux. I...
