People with Asthma have very sensitive airways that are constantly on the verge of over-reacting to asthma triggers. It doesn't take much for the airways to become inflamed, constricted, and filled with fluid. The constriction (think of wring a rag dry) is the narrowing of the bronchial tubes that leads to the bronchial tree. Making breathing very difficult.
Asthma
because of nature !
Differing air temperature causing cold air to sink, and warm air to rise is the main cause of air movement.
Its will not cause evaporation or condensation. What will happen is that it will cause some moist air because hot fonts and cold fonts create moist air. you can see it all the time on the news in the summer.
Heat and cold air.
The North America air masses is what causes cold waves. This is in the Central Eastern United States.
no
because of nature !
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
Bronchoconstriction is due to an activation of parasympathetic nervous system.
Parasympathomimetics are cholinergics. They effect the muscarinic receptors sites and cause bronchoconstriction or cause the closing of airways. Parasympatholytics are anticholinergics. They block the muscarinic receptor sites and prevent bronchoconstriction or prevent closing of airways. Source: I'm a 3.8 gpa Respiratory Therapy student.
the cause is when warm wet air and dry cold collide

There are two types of air masses: COLD AIR AND WARM AIR.Cold Air Masses-Cold air masses can cause thunderstorms and even tornadoes.Warm Air Masses-Warm air masses can bring many hours of steady rain and snow.
Pressure differences between warm and cold air masses cause fronts or high/low pressure systems. A warm front is when a warm, moist air mass slides up and over a cold air mass, and a cold front is the opposite.

No. cP means continental polar. Such an air mass can cause a cold spell.
The air behind a cold front is cool and dry.
