Novaya Zemlya effect and sunsets.
Systematics of the Novaya Zemlya (NZ) effect are discussed in the context of sunsets. We distinguish full mirages, exhibiting oscillatory light paths and their onsets, the subcritical mirages. Ray-tracing examples and sequences of solar images are shown. We discuss two historical observations by Fridtjof Nansen and by Vivian Fuchs, and we report a recent South Pole observation of the NZ effect ...
متن کاملNovaya Zemlya effect: analysis of an observation.
The Novaya Zemlya effect, historically identified with the premature rebirth of the sun during the polar night, is a long range optical ducting phenomenon in the lower atmosphere. An occurrence of the effect was observed at Tuktoyaktuk, Canada (69 degrees 26'N, 133 degrees 02'W) on 16 May 1979, when the minimum solar altitude was - 1 degrees 34'. The sun's image remained above the horizon, with...
متن کاملFusion of Multi-Source Satellite Data and DEMs to Create a New Glacier Inventory for Novaya Zemlya
Monitoring glacier changes in remote Arctic regions are strongly facilitated by satellite data. This is especially true for the Russian Arctic where recently increased optical and SAR satellite imagery (Landsat 8 OLI, Sentinel 1/2), and digital elevation models (TanDEM-X, ArcticDEM) are becoming available. These datasets offer new possibilities to create high-quality glacier inventories. Here, ...
متن کاملEstimating the relative yields of Novaya Zemlya tests by waveform intercorrelation
The relative size of 15 underground nuclear explosions at the Novaya Zemlya test site is determined by applying a relative waveform analysis called intercorrelation to 566 teleseismic short-period P-waves. The waveforms are corrected for the effects of pP interference and yield scaling of the explosion source functions so that signals from different events recorded at the same station can be an...
متن کاملThe Novaya Zemlya Bora and its impact on Barents Sea airsea interaction
[1] Novaya Zemlya is a mountainous archipelago in the EasternArctic.Weather station data indicates that southeasterly high-speed winds are frequent, especially during the winter. Although it has been proposed that a bora is responsible for these winds, there has been no quantitative analysis of the flow in the region. Here we present the first high-resolution climatology of the three-dimensiona...
