High occurrence of cough symptoms was observed in athletes during cold-air training.
In winter eastern France especially may come under the influence of the continental high-pressure system, which brings extremely cold conditions and temperature inversions over the cities, during which cold air is trapped below warmer air, with consequent fogs and urban pollution.
Comparing running outside during winter with cold air as a stimulus to spring with pollen, summer with ragweed or fall with mold induces measurement error.
This is consistent with observations in this study; namely, flippers tended to be cooler during exposure to cold air and warmer than the air when exposed to warm environment.
The northern Plains' wheat crops rely on snow cover to protect them from cold air during their dormant winter months, say forecasters, who warn of possible higher prices because of the odd weather.
The thatch prevents nest overheating by the incoming solar radiation and avoids losses of the accumulated heat into the cold air during night.
In fact, inhalation of large volumes of cold air during exercise is thought to be the inciting event of exercise-induced asthma [ 16].
Windows can be a source of cold air during the winter months.
An investigation was conducted to develop ventilation systems to prevent cold air drafts during the winter season and create a suitable atmosphere inside the broiler rearing building.
The stable high-pressure weather conditions prevailing over central Europe and the Alps during autumn and winter create cold air masses that result in lowland fog, a climatic phenomenon with widely varying consequences.
