It is winter in Chennai ~ mornings are
chill, people say so ! In Chennai,
people don’t wear woolen sweaters or shawls nor use mufflers [used to see
them a couple of decades ago] ~ the ear
caps that have flooded the market sell……….. the lowest of the month at Chennai is recorded
to be : 20.8°C (5/1/13). Cold wave and harsh weather conditions
continued to throw life out of gear in North India
with the minimum temperature dipping to 2.4 degrees Celsius in the national
capital on Monday. The minimum
temperature in Delhi
improved partially from Sunday’s 1.9 degrees to 2.4; it still remains five degrees below normal.
Making the mater worse, icy-winds forced people to stay inside their homes in Delhi .
Elsewhere is the Laizhou Bay, the
southern arm of the Bohai Sea which is a large relatively shallow extension of Korea
Bay (Northern Yellow Sea). The Yellow Sea is the name given to the northern
part of the East China Sea, which is a marginal sea of the Pacific
Ocean . Sea ice is simply
frozen ocean water. It forms, grows, and melts in the ocean. Sea ice occurs in
both the Arctic and Antarctic. On average, sea
ice covers about 25 million square kilometers (9,652,553 square miles) of the
earth, or about two-and-a-half times the area of Canada . Because most of us do not
live in the polar regions, we may live for several decades and never see sea
ice. Sea ice grows during the winter
months and melts during the summer months, but some sea ice remains all year in
certain regions. About 15 percent of the world's oceans are covered by sea ice
during part of the year.
Chinese media reports of heavy ice conditions in Laizhou
Bay , Bohai sea, East
China sea . Some 1,000 vessels reportedly are stuck in ice field of
some 300 sq kilometers. Mostly those trapped are fishing vessels, but there are some bigger vessel as well. China
Meteorological Administration on Friday said the national average was -3.8
degrees Celsius (25 degrees Fahrenheit) since late November, the coldest in
nearly three decades. In some areas —
northeastern China , eastern Inner Mongolia , and north part of far-western Xinjiang
province — the low has hit -40 degrees C (-40 degrees F), the administration
said. In southwest China ’s Sichuan
province, more than 1,000 tourists were stranded Wednesday in a scenic
mountainous area because of icy road, the state-run Beijing News reported. At some other places, snowstorm have disrupted
air and road traffic.
Thaw : - to change from a frozen solid to a liquid
state by gradual warming ; to lose stiffness, numbness by being warmed; to
become warm enough for snow and ice to melt. There is the Northern Sea Route, a shipping lane officially defined by Russian
legislation from the Atlantic Ocean to the Pacific Ocean specifically running
along the Russian Arctic coast from Murmansk on the Barents Sea ~ the entire
route lies in Arctic waters and parts are free of ice for only two months per
year.
At Laizhou bay, cold snap has created a
layer of thick sea ice expanding to 291 square km with apprehensions that it is
continuing to grow; it is stated that the ice this year is the worst the area has
experienced in three years. This brutal cold snap has trapped around 1000
ships, stranded and unable to move in the frozen ocean. The most unusual chill weather experienced
with temperatures plunging to their lowest in almost 3 decades have caused
this. There were some reports of dramatic
rescue of young deer stranded on frozen reservoir was in vain as it had to be
humanely euthanized due to severe injuries. On the sky, over 140 flights from the state
capital airport in central Hunan
province were delayed, while heavy snowfall forced the closure of some sections
of the Beijing-Hong Kong-Macau Expressway, the China Daily said.
There is the sea ice and then we have
heard of icebergs - most basic
difference is that sea ice forms from salty ocean water, whereas icebergs,
glaciers, and lake ice form from fresh water or snow. With weather – hot,
hotter and hottest in Chennai, such news are really new to us.
