This work is dedicated to a study of near-equatorial electron distribution in the ionosphere under the radiation belts. Sporadic 100 keV electron splashes have been registered at near-equatorial latitudes. The longitudinal dependence has been found in the distribution of these splashes. The results have been compared with satellite data of thunderstorms registration, through this it was found t...

The title compound, [Os(3)(C(25)H(22)As(2))(CO)(10)], contains a triangle of singly bonded Os atoms; both arsine ligands are equatorial with respect to the Os(3) triangle. Each arsine-substituted Os atom bears one equatorial and two axial terminal carbonyl ligands, whereas the unsubstituted Os atom bears two equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two...

Fluorescently labeled myosin moved and accumulated circumferentially in the equatorial region of dividing Dictyostelium cells within a time course of 4 min, followed by contraction of the contractile ring. To investigate the mechanism of this transport process, we have expressed three mutant myosins that cannot hydrolyze ATP in myosin null cells. Immunofluorescence staining showed that these mu...

Tropical cyclones (TCs) actively contribute to the dynamics of Earth’s coupled climate system. They influence oceanic mixing rates, upper-ocean heat content, and air–sea fluxes, with implications for atmosphere and ocean dynamics on multiple spatial and temporal scales. Using an ocean general circulation model with modified surface wind forcing, we explore how TC winds can excite equatorial oce...

Abstract: The skill with which a coupled ocean-atmosphere model is able to predict precipitation over a range of time scales (days to months) is analysed. For a fair comparison across a seamless range of time scales, the verification is performed using data averaged over time windows equal in length to the forecast lead time. At a lead time of one day, skill is greatest in the extratropics arou...

Although the seasonal cycle of the equatorial Atlantic and Pacific Oceans have many similarities, for example, an annual signal is dominant at the equator even though the sun ‘‘crosses’’ the equator twice a year, different processes determine the seasonal cycles of the two oceans and in the Atlantic different processes are important in the east and west. In the Gulf of Guinea in the eastern equ...

This chapter examines the sensitivity of tropical Pacific interannual variability to changes in the climatological background state. Chapter 5 showed that although a wide variety of climate perturbations can affect the equatorial Pacific, the equatorial structure of the response tends to be similar in each case. Due to strong coupled feedbacks like those active in ENSO, the Pacific climatology ...

Equatorial ionosphere poses a challenge to any algorithm that is used for tomographic reconstruction because of the phenomena like the Equatorial Ionization Anomaly (EIA) and Equatorial Spread F (ESF). Any tomographic reconstruction of ionospheric density distributions in the equatorial region is not acceptable if it does not image these phenomena, which exhibit large spatial and temporal varia...

This paper extends Leovy’s theory on Venus’ equatorial superrotation by analytically examining additional terms in the mean zonal momentum equation that stably balances the momentum source of pumping by thermal tides. The general analytical solution is applied to the atmospheres of both Venus and Saturn’s moon Titan. The main results are: (i) Venus’ equatorial superrotation of 118m s 1 results ...
