Explanation / Answer

Answers:

The primary reason for the increase in the number of tornadoes over two decades is climate change and subsequent increase in global temperature over past years. Tornadoes generate from supercell thunderstorms and in United States, tornadoes mostly occur in Oklahoma where warm current from Gulf of Mexico collides with cold airs coming from north and west. Climate change and subsequent global warming causes increase in ocean temperature which enhances evaporation. As a result, along with increased heat, moisture content also increases, which causes thunderstorm and sometimes tornado, and if this continuous increasing occurs, the situation will further worsen and intensities of tornadoes will also increase.

Part-5

a) Highest temperature occurs in the month of July. The temperature is about 25o C.

b) Lowest temperature occurs in the month of January. The temperature is about -2o C.

c) The annual temperature of Chicago varies significantly from season to season. In summer months, the temperature is generally around 20o C with its peak at 25o C in July. In winter months, it is around 0o C with its peak at -2o C in January. The autumn and spring months generally experience cool weather with temperature ranging from 5o C to less than 20o C.

d) The month of May receives greatest amount of precipitation of about 10 cm (4 in).

e) Despite the fact depicted from the graph, that, there is no significant difference in precipitation from seasons to seasons, the precipitation is concentrated mostly from summer months (covering the whole summer of May, June, July and August) to the start of autumn (September) with precipitation range of 8-10 cm.

f) The summer is hot, with one month having temperature of about 25o C (above 22o C) and four months having temperature around 20o C (above 10o C) with not so significant precipitation difference from seasons to seasons. So, according to Koppen Climate Classification scheme, it falls under Hot Summer Humid Continental Climate, Dfa.

15.

a) As the name suggests, the climate is Tropical Rainforest Climate, Af.

b) In the subtropical high-pressure system, most of the hot deserts are present. So, the climate is Hot Desert Climate, BWh.

c) Northern coniferous forest areas are present in northern parts of North America, north-central Eurasia. The climate type is Subarctic climate, Dfc.

d) The climate type is Subarctic Oceanic Climate, Cfc, where in winter, temperature is above 0o C and in warmer months it is above 10o C and no significant precipitation difference between seasons.

e) The climate is Tundra Climate, ET, where temperature of warmest months lie between 0o c and 10o C.

f) Potential evaporation exceeds precipitation in dry land which experience a prolonged dry season (of 7-8 months of no rainfall). So, the climate type is Tropical Dry Savanna Climate, As.

g) The climate type is Humid continental climate, D as the windward side of the continent experiences rainfall.

The type of cloud is cumulonimbus. This cloud forms when stable, moist air rises because of warmer mountain air which itself causes the air to rise. And ultimately the sir, when reaches the dewpoint it results in formation of this type of clouds.
