The El Niño–La Niña asymmetry was estimated in the 10 different models participating in the Coupled Model Intercomparison Project (CMIP). Large differences in the “asymmetricity” (a variance-weighted skewness) of SST anomalies are found between models and observations. Most of the coupled models underestimate the nonlinearity and only a few exhibit the positively skewed SST anomalies over the t...
[1] We present observations of auroral omega bands on 28 September 2009. Although generally associated with the substorm recovery phase and typically observed in the morning sector, the features presented here occurred just after expansion phase onset and were observed in the midnight sector, dawnward of the onset region. An all‐sky imager located in northeastern Iceland revealed that the omega...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
Bird migration was recorded by tracking radar and visual observation at 23 sites in the region of the Northwest Passage, between Baffin Island and Herschel Island in the Beaufort Sea. The studies took place during a ship-based expedition from 29 June to 3 September 1999. A total of 692 tracks (average duration 160 s) of bird flocks on postbreeding migration were recorded. Eastward migration was...
Short-term (1–10 day) forecasts are made with climate models to assess the parameterizations of the physical processes. The time period for the integrations is that of the intensive observing period (IOP) of the Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE). The models used are the National Center for Atmospheric Research (NCAR) Community Climate Mod...
This paper chooses the manufacturing added value as the main research indicator, using gravity analysis method to analyze the spatial evolution of manufacturing industry in Guangdong province from 2006 to 2015, decomposing the manufacturing gravity and calculating the grey correlation degree. The results show that: 1) manufacturing gravity is mainly distributed in Dongguan, it is characterized ...
The nuclear stellar disc (NSD) is a dense structure at the centre of our Galaxy. Given its proximity, it constitutes unique laboratory to understand other galactic nuclei. Nevertheless, high crowding and extinction hamper study, even morphology kinematics are not yet totally clear. In this work we use NSD red clump stars, whose intrinsic properties well known, trace compute distance towards edg...
