Climate, Weather, and Geography

• Sirocco is a Mediterranean wind that comes from  the Sahara and can reach hurricane speeds in North Africa  and  Southern Europe especially during the summer season..
  
• The Sirocco causes dusty dry conditions along the northern coast of Africa, storms in the Mediterranean Sea, and cool wet weather in Europe. 
  
• The term Sirocco  is a name given to hot and subsequently humid southeast to southwest winds originating as hot, dry desert-air over Northern Africa, flowing northward into the southern Mediterranean basin.
  

sirocco is a hot wind, often dusty or rainy, blowing South, from North Africa across the Mediterranean to southern Europe. mistral is a cold northwesterly wind usually strong, that blows through the southern France into the Mediterranean, mainly in winter.

Oceanic climate

The Arctic type of climate is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. The Arctic type of climate in Europe is also called as Tundra because Tundra region has the same type of climate as Arctic. The northern part of the continents within the polar region is known as the Tundra region. Tundra regions are found in the northern and southern hemispheres between the ice-covered poles and the coniferous forests.

The North Atlantic Drift is a warm ocean current that brings relatively warm water to the Norwegian coast. This prevents the ports from freezing even at high latitudes where other regions experience ice.

During the winter freezing time the polar region are covered by caps which is of water, and carbon dioxide. They appear white.

Due to greenhouse effect, the sunlight that Earth gets in daytime is trapped inside the Earth's atmosphere and in night the same energy keeps the Earth's surface warm.

The Gangotri glacier in the Himalayas has started melting because of global warming.

The troposphere is the lowest layer of the atmosphere where almost all weather phenomena, including thunderstorms, rain, and clouds, occur due to the presence of water vapor and convection.

Troposphere is the lowest layer in the earth's atmosphere. it is the same layer in which all the change in weather takes place. Lapse rate is the rate at which the temperature drops due to the difference in elevation. the more the altitude the more the drop in temperature is there. The lapse rate of $6.5$ is there for the level of $0$ to  $11,000$ m. This is the region in which troposphere lies. 

The tropopause is the boundary in the Earth's atmosphere between the troposphere and the stratosphere. Therefore it would serve as the upper part of the troposphere. So the correct answer is ' Upper part of troposphere'. 

Weather is the state of the atmosphere which can change on a daily basis. It describes the degree to which it is hot or cold , humid or dry, calm or stormy etc. therefore, it cannot be the seasonal change in the atmosphere as that would mean changing of seasons. It cannot be average variation of atmospheric conditions as that would be climate change. It cannot be all of the above because two options indicate season and climate. So the correct answer is 'Short term properties of atmosphere.'

Cataracts and blindness are among the most common eye diseases associated with further ozone layer depletion and increased UV-B at the Earth's surface.  A 1% decrease in stratospheric ozone may result in 100,000 to 150,000 additional cases of blindness due to eye cataracts worldwide. The ozone layer is responsible for absorbing harmful ultraviolet rays, and preventing them from entering the Earth's atmosphere.

Forecasts are estimates of future events and are inherently subject to uncertainty. They are rarely perfect, and their accuracy generally decreases as the time horizon increases.
