Abstract One of the most prominent mesoscale phenomena in coastal zone is sea-breeze/land-breeze circulation. The pattern and its implications for weather areas are well described, with mesoscale-resolving operational NWP models circulation can be captured. In this study, a straightforward method to identify sea land breezes based on change wind direction column above grid point coastline prese...
Abstract Growing evidence indicates that the atmospheric and oceanic circulation experiences a systematic poleward shift in warming climate. However, complexity of climate system, including coupling between ocean atmosphere, natural variability land-sea distribution, tends to obfuscate causal mechanism underlying shift. Here, using an idealised coupled aqua-planet model, we explore shifting cir...
Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Most of them are discovered as incidental findings during coronary angiographic studies or at autopsies. We present herein the case of a 70-year-old man with symptomatic severe aortic valvar stenosis whose preoperative coronary angiogram revealed a so far unreported coronary anomaly circulation pattern.
Hepatitis E virus sequences were detected by RT-PCR in 14/15 (93%) of untreated sewage samples from Edinburgh, Scotland, UK. Phylogenetic analysis of amplicons at limiting dilution revealed the co-circulation of multiple variants of HEV-3, with a pattern of diversity matching that observed in a local cohort of HEV-infected hepatitis patients.
The role of General Circulation Models (GCMs) has become predominantly important as the practical interest in regional impacts from anthropogenic greenhouse gases such as carbon dioxide (CO2) grows. This first report documents the quality of GCMs as a tool for describing and predicting ‘global warming’ and the related geographical pattern of climate change from the CO2 added to Earth’s atmosphere.
[1] Spur and groove (SAG) formations are found on the fore reefs of many coral reefs worldwide. Although these formations are primarily present in wave-dominated environments, their effect on wave-driven hydrodynamics is not well understood. A twodimensional, depth-averaged, phase-resolving nonlinear Boussinesq model (funwaveC) was used to model hydrodynamics on a simplified SAG system. The mod...
13 The Arctic Oscillation (AO) under increased atmospheric concentration of greenhouse gases 14 (GHG) was studied by comparing an ensemble of simulations from 13 coupled general circulation 15 models with GHG at the pre-industrial level and at the late 20th century level, for November to 16 March. The change in the linear AO pattern as GHG increased reveals positive sea level pressure 17 (SLP) ...
Spur and groove (SAG) formations are found on the forereefs of many coral reefs worldwide. Modeling results have shown that SAG formations together with shoaling waves induce a nearshore Lagrangian circulation pattern of counter-rotating circulation cells, but these have never been observed in the field. We present results from two separate field studies of SAG formations on Palmyra Atoll which...
BACKGROUND Bovine herpesvirus 5 (BoHV-5) is a member of the subfamily Alphaherpesvirinae responsible for meningo-encephalitis in young cattle. The first case of bovine meningo-encephalitis associated with a herpesvirus infection was reported in Australia. The current geographical distribution of BoHV-5 infection is mainly restricted to South America, especially Brazil and Argentina. Outbreaks o...
