A Monster Snow Storm Hits The U.S

Current cloud system in North America NOAA, Earth Google

While here in Canada (January 26, 2015) a very cold and high pressure system has predominated       (temperature  minus 12 to 14 Celsius in southern Ontario), our coastal neighborhood experiencing a very severe snow storm with high winds. It is expected that 30 to 90 centimeter of snow will fall on Northeastern territory of the U.S. Worm and moist air of Atlantic ocean plays a major role in severeness of snow.Wind speed depends of closeness and strength of high and low air pressure. Closer and higher difference between these two pressures systems result in winds to pick up their speed in direction of low pressure.Strong low pressure has been formed in Atlantic coastal area of the United States. At the same time a high pressure hanging around eastern part of Canada not too far from Atlantic ocean.This high pressure sending strong wind to the north east of the US, where a very low system is waiting to attracts wind and moisture to form a windy, cloudy sky. Winds blow toward the center of low pressure. As a result, wind from Atlantic ocean hits the coastal areas while trying to spin around the low pressure center.

Collision between two system lowers the temperature while increasing the relative humidity. A cold air mass that reached to a saturation point will precipitate in form of rain or snow. In the northeast scenario very cold weather forms snow blizzards which might be reached to a historical record. we have to waite and see what the sky has in its store for us.

It happened in seconds

A big volcano eruption released a hug amount of ashes and dusts in just seconds. Colima volcano in Mexico, has a long history of eruption but never been captured in a webcam. Colima  located in the Western Mexico region on Mexico’s central Pacific coast. A webcam which is focuses on the volcano activity caught its spectacular eruption. Plumes of ash went up to 5 Kilometer into atmosphere while the resulted cloud grew up to nine kilometers.It is reported that since 1585 it has erupted at least 30 times.

If it is cold,Take care of your Nose more!

As seasons change Jet-stream also changes its course. Jet-stream these days flowing down to the USA border with Mexico. As a result of it, cold fronts (which have high pressures) following (indeed boarding) the Jet-stream while increasing its domain from Canada to Texas in the USA.This week temperature in Toronto reached to minus 16 Celsius, so far, and some provinces experiencing minus 20 and below.Protecting yourself from extreme weather is a common sense but protect your nose too. Keeping your nose worm halts a kind of virus( rhinovirus)  which grows inside of peoples' nose. Cold weather activate the virus.At the same time your body immune system is weak as the temperature goes down. Consequently the common cold make you busy with running nose, sneezing and coughing. Scientists at  Preceedings of National Academy of Sciences of The USA concludes:

Rhinovirus is the most frequent cause of the common cold, as well as one of the most important causes of asthma exacerbations. Most rhinovirus strains replicate better at the cooler temperatures found in the nasal cavity than at lung temperature, but the underlying mechanisms are not known.
