Eastward-propagating planetary waves (EPWs) were investigated prior to the boreal January 2009 major sudden stratospheric warming (SSW) event simulated by National Center for Atmospheric Research's Whole Atmosphere Community Climate Model with specified dynamics. About 22 days before SSW onset, a background flow jet maxima around upper polar stratosphere and subtropical mesosphere developed due...

Abstract A novel technique is developed to identify equatorial waves in analyses and forecasts. In a real-time operational context, it not possible apply frequency filter based on wide centered time window due the lack of future data. Therefore, wave identification performed primarily spatial projection onto mode horizontal structures. Spatial alone cannot distinguish eastward- from westward-mo...

The Tasman Fold Belt System makes up most of the crust of eastern Australia and consists of three broadly north–south-oriented fold belts (Figure 1) that record a continuing history of crustal growth from 600 Ma until at least the Triassic. Taking into account the 800–600 Ma Adelaide Rift Complex further west, this eastward younging of the Geological Society of Australia Special Publication 22,...

Many transmeridian travellers, including top athletes, regularly take melatonin to reduce negative jet lag symptoms. Standard (rather than individually tailored) doses are often used. We examined the effects of a standard dose of melatonin on the body temperature rhythms of 12 elite biathletes (eight men and four women) after an eastward transmeridian flight to an international competition. The...

[181] The preoccupation of Alfonso el Batallador with purely Aragonese affairs continued until the death of his former wife, roughly two years after the reconquest of Sigüenza. The status quo in LeónCastilla apparently satisfied the monarch of Aragón, for despite some provocation he busied himself almost exclusively with attempts at rounding out his newly swollen realm southward and eastward an...

OI 630.0 nm airglow observations, from a new observatory at Bom Jesus de Lapa, were used to study the interaction between EPBs (Equatorial Plasma Bubbles) and MSTID (Medium-Scale Traveling Ionospheric Disturbance) over Northeast region in Brazil. On night of September 16 17, 2020, an EPB was observed propagating eastward, apparent fossil stage, until it interacted with dark band electrified (eM...

Abstract The present study aims to reveal horizontal sporadic E (Es) movements driven by atmospheric diurnal/semi-diurnal tides using a three-dimensional (3D) ionospheric model. Horizontal Es have been investigated since the mid-twentieth century, variety of 1D/2D observational techniques. However, there are no comprehensive studies that explain different results asserted observations. Herein, ...

Since the establishment of Turkish Republic, it has two options for international regions, “westward” and “eastward”, one which dominated at different times in its history. The change Republic Turkey’s Perception International Regions encompasses period from Kemal to post-Kemal era, a ’westward’ an ’eastward’ strategy, Euro-Western focus return Middle East-Islamic world. Turkey regional perspec...
