Air-sea-ice interaction processes in the Southern Ocean are investigated utilizing space-observed surface winds, sea ice concentration, and sea surface temperature (SST) from September through December, 1996. The sea ice edge (SIE) shows three ice-extent maxima around the Antarctic during September and October when sea ice coverage is maximum. They are located in the central Indian Ocean, east ...

Intravenous injection of heparin (100 U/kg) into normal volunteers resulted in an increase of platelet factor 4 (PF4) level in platelet-poor plasma from a mean value of 18.1 +/- 6.6 ng/ml before the injection to 257.9 +/- 68.3 ng/ml at 5 min after injection. PF4 antigen isolated from "postheparin plasma" by adsorption on heparin-agarose and elution with 2.0 M NaCl and "authentic PF4" isolated f...

The extratropical annular modes are coupled with a distinct pattern of climate anomalies that spans the circulation of the tropical troposphere. The signature of the annular modes in the tropical troposphere exhibits a high degree of equatorial symmetry. It is associated with upper-tropospheric zonal wind anomalies centered about the equator, midtropospheric temperature anomalies located ;208N ...

Pulse oximetry during breath-holding (BH) in normal residents at high altitude (3510 m) shows a typical graph pattern. Following a deep inspiration to total lung capacity (TLC) and subsequent breath-holding, a fall in oxyhemoglobin saturation (SaO(2) is observed after 16 s. The down-pointed peak in SaO(2) corresponds to the blood circulation time from the alveoli to the finger where the pulse o...

BACKGROUND Most experimental stroke research is carried out in rodents, but given differences between rodents and human, nonhuman primate (NHP) models may provide a valuable tool to study therapeutic interventions. The authors developed a surgical method for transient occlusion of the M1 branch of middle cerebral artery (MCA) in the African green monkey to evaluate safety aspects of intravenous...

In this work, the authors investigate changes in the interannual relationship between the East Asian summer monsoon (EASM) and the tropical Indian Ocean (IO) in the late 1970s. By contrasting the correlations of the EASM index (EASMI) with the summer IO sea surface temperature anomaly (SSTA) between 1953–1975 and 1978–2000, a pronounced different correlation pattern is found in the tropical IO....

1 ABSTRACT A combination of analytical and numerical techniques are used to efficiently determine the qualitative and quantitative behaviour of a one-basin zonally averaged thermohaline circulation ocean model under various forcing regimes and over a large region of parameter space. In contrast to earlier studies which use time stepping to find the steady solutions, the steady state equations a...

The Beagle Channel is a long and narrow interoceanic passage within the Tierra del Fuego archipelago in southernmost tip of South America. A high-resolution 3D hydrodynamic model based on finite elements method was applied to investigate residual circulation, water fluxes transport time scales inside this channel. Numerical solutions were analyzed at seasonal scale results compared with observe...

This paper explores the COVID19 transmission pattern and circulation dynamics in Euclidean space at lower peninsula of Michigan by using divergence curl concept vector field. The volume flux can be calculated for each county divergence. results shows Wayne had highest (162660), Kent second (152540), Saginaw third (103240), is positive which means virus was transmitted from these counties to oth...

Efforts to intercompare many existing circulation type classification (CTC) methods have found no consistency in their outcomes. Therefore, when confronted with a task classify atmospheric types, it is difficult find clear guidelines. This study explores the ways of increasing between and obtaining physically meaningful practically useful results. By applying range CTC sea-level pressure fields...
