____ cool, dry fall air in Ashland, Ohio

____ daytime highs only reaching the single digits in Ashland, Ohio

____ drought with record high temperatures in the desert southwest

____ persistent cold, damp weather and drizzle in Boston

____ hot, muggy weather in Ashland, Ohio

____ summertime afternoon thunderstorms in the southeastern U.S.

____ 65F in January in Ashland, Ohio

____ lake effect snow in northeastern Ohio

____ pleasantly cooler temperatures and lower humidity after several hot & humid summer days

Explanation / Answer

a) mP -

Cool and moist, often originating as continental polar air over the North American and Asian land masses and is modified as it moves out over the Atlantic and Pacific Oceans. Heated by the relatively warm water bodies this air mass becomes rather unstable resulting in blustery showers over the sea and windward coasts.

b) cP-

Cold and dry, originating from high latitudes, typically as air flowing out of the polar highs. This air mass often brings the rattleing cold, dry and clear weather on a perfect winter day and also dry and warm weather on a pleasant day in summer.

c)cA-

Extremely cold temperatures and very little moisture. Originating over the Arctic ocean in winter, when high pressure dominates and differs only slightly from the continental polar (cP) air masses that develop over Siberia and northern Canada.

d) cT-

Hot and very dry, orginating from the arid and desert regions during summer. The least common air mass to affect the British weather. However, approaching from the south and south-east in summer it can bring record heat to southeast Britain, particulary in late-summer.

e)mP

f)mT-

Mild and damp in winter, very warm and muggy during summer. Originating from the Azores this air mass approaches the British Isles from the west, leading to overcast skies with prolonged rain for the western half of the country and to many clouds, sometimes broken with drizzle for the eastern half. In summer tropical maritime air often produces warm weather with abundant sunshine in the southeast.
