The 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 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 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 کاملDo Housing Bubbles Affect Consumption?
Standard optimzing models of consumption postulate that consumption is a function of wealth and implicitly assume that wealth is comprised of assets whose market price coincides with the fundamental price, defined as the expected present value of future dividends. We use a simple theoretical framework to show that when the market price deviates from the fundamental price, consumption behavior w...
