IntroductionCold air inhalation (CAI) during exercise increases cardiac mortality. The pathophysiology remains unclear, but may reflect adverse changes in microvascular resistance (MVR). We compared the accuracy of two novel intra-coronary measures of MVR to predict microvascular dysfunction (MVD). We ...
For many locations around the globe some of the most severe weather is associated with outbreaks of cold air over relatively warm oceans, referred to here as marine cold-air outbreaks (MCAOs). Drawing on empirical evidence, an MCAO indicator is defined here as the difference between the skin ...
Another hypothesis suggests that the predominance of the negative phase of the NAO, which resulted in frequent cold air outbreaks over Eurasia during the hiatus period, may have been forced, at least in part, by the pattern of tropical Pacific SSTs9. This hypothesis, however, contrasts the find...
The decreased occurrence is likely associated with transient warming over East Asia that has been observed to follow SSWs31 (e.g., there is a transient decrease in the anomalous cold air mass flux towards high-latitude East Asia over the first 2 weeks following the polar vortex anomalies, ...

Cold front weather is an area of transition between cold air and warmer air. Weather maps generally show warm and cold fronts, with a cold front appearing as a blue line, or as a blue line with blue triangles. The air behind the front is usually colder a
air quality, the temperature, the humidity, the room pressure, and even the lighting level are the main postharvest problems of flower cold chains. For instance, the lighting parameter directly affects the quality of the fresh flowers, but the bacterial growth should be under the control with ...
Cold-air mesocyclones remain a forecasting challenge in the southern hemisphere middle and higher latitudes, where conventional observations are lacking. One way to improve mesocyclone predictability is to determine their larger-scale circulation environments and associations with teleconnection patterns. To ...
On a cold evening with snow floating in the air, I got(stick) on the road because of a flat tire(轮胎). I attempted(seek) help from the passing cars, but no one stopped. As I was about to give up hope, a man(drive) an old dirty car came to my aid. To be honest, I was ...
Instead of dry air from a tank, room air was used for hyper- ventilation because the children objected to the "taste" of the compressed air, and because when the air with an average room temperature of +20 k 2°C and 60 + 10% relative humidity was cooled to around -15"C, the ...
