The convection electric field is transmitted to low latitude near-instantaneously by the TM0 mode waves in the Earth-ionosphere waveguide, resulting in high correlation of the DP2 fluctuations between high latitudes and equator during storm and substorms.
Our analysis of the DMSP precipitating fluxes shows how the equatorial boundary of the auroral oval is moving toward the equator during the storm; this is in agreement with the classical picture of the auroral oval location.
They also discussed the characteristic changes in the F layer peak height over the equator during this storm event and discussed that the F layer peak height over the equator first decreased under a strong prompt penetration westward electric field, which was followed by a significant height increase under an eastward electric field.
The minimum latitude of the trough position for sheath storms is closer to the equator, although the average storm intensity is weak.
I was in Sulawesi, Indonesia, on the Equator, sweating up a storm, when I got the call that the Chinese authorities would finally meet with me about a permit I was seeking to run the Yangtze.
This "force" is zero at the equator, so any infant storms there don't get the necessary kick to start spinning.
Abrupt warming events in the Arctic pull the meteorological equator — a band of tropical storm clouds that circle the globe near the Equator — farther north, and, along with it, the rainfall patterns associated with the Asian summer monsoon.
An investigation using measurements from multiple instruments over the American sector showed that spread-Fs were often observed the nights before and during storms near the equator, in which the foF2 was less than 8 MHz and the h′F was lower than 300 km (de Abreu et al. 2017).
The separation of the cyclone from the warm air toward the Equator, however, eventually leads to the storm's decay and dissipation (E) in a process called cyclolysis.
The overshielding electric field together with the R2 FACs causes reversal of the ionospheric electric field at midlatitude and the counter electrojet at the equator during substorm expansion phase and storm recovery phase.
