Since the slowing of the trend of increasing surface air temperature (SAT) in the late 1990 s, intense interest and debate have arisen concerning the contribution of human activities to the warming observed in previous decades. Although several explanations have been proposed for the warming-trend slowdown (WTS), none has been generally accepted. We investigate the WTS using a recently develope...

[1] The ability of general circulation models (GCMs) to reproduce the observed strong correlations of Eurasian snow extent in the fall to wave activity and Northern Annular Mode anomalies in the following winter is studied. The observed correlations have been hypothesized to involve two parts: a Rossby wave pulse generated in the troposphere in response to snow-forced surface cooling and a coup...

Natural forcing from solar and volcanic activity contributes significantly to climate variability. The post-eruption cooling of strong eruptions was hypothesized have led millennial-scale variability during Glacials. Cooling induced by eruption is potentially weaker in the warmer climate. underlying question whether climatic response natural state-dependent. Here, we quantify under Last Glacial...

This study examines whether exhausting exercise in cold air induces bronchial obstruction and changes in exhaled [NO] and in exhaled NO output (V'NO). Thus, eight well-trained males performed two incremental exercise tests until exhaustion, followed by 5 min of recovery in temperate (22 degrees C) and cold (-10 degrees C) environments, at random. At -10 degrees C, they were dressed in warm clot...

The paper presents some investigation results on the properties of forced cooling systems dedicated to electronic devices. Different structures such systems, including Peltier modules, heat sinks, fans, and thermal interfaces, are considered. Compact models formulated. These take into account a multipath transfer make it possible compute waveforms device’s internal temperature at selected value...
