This evening there were
sharp showers in the city – for close to half an hour, it rained so heavily
that one felt that city could be inundated at many places !
Precipitation is water
released from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Precipitation is the main way atmospheric water returns to the surface of the
Earth. Most precipitation falls as rain. Rain and snow are key elements in the
Earth's water cycle, which is vital to all life on Earth. Rainfall is the main
way that the water in the skies comes down to Earth, where it fills our lakes
and rivers, recharges the underground aquifers, and provides drinks to plants
and animals.
Although most people
think raindrops look like teardrops, they actually look more like chocolate
chip cookies. Like raw balls of dough dropped on a cookie sheet, the smallest
raindrops, up to 1 millimeter in diameter, are actually spherical. At 2
millimeters raindrops start to flatten, because of the air pressure pushing up
on them as they fall to Earth. This effect is increased at 3 millimeters, and
depressions form on the bottom of the drops as the air pushes up on the drops
harder. At 4 millimeters raindrops actually distort into a shape that looks
like a parachute. When they get to be about 4.5 millimeters in diameter,
raindrops are so big that they break apart into two or more separate drops
!!
Rain is liquid
precipitation: water falling from the sky. Raindrops fall to Earth when clouds
become saturated, or filled, with water droplets. Millions of water droplets
bump into each other as they gather in a cloud. When a small water droplet
bumps into a bigger one, it condenses, or combines, with the larger one. As
this continues to happen, the droplet gets heavier and heavier. When the water
droplet becomes too heavy to continue floating around in the cloud, it falls to
the ground. Human life depends on rain. Rain is the source of fresh water for
many cultures.
The northeast monsoon in
Tamil Nadu has intensified leading to widespread rainfall across several
districts including Coimbatore, Tiruppur, Nilgiris, Madurai, Nagapattinam among
others since Wednesday night. Due to the heavy rainfall, schools in Madurai,
Coimbatore, Theni, Tiruppur, Dindigul declared holidays. In Nilgiris and in
four taluks of Udhagamandalam, Coonoor, Kothagiri, Kundah, holidays were
declared for both schools and colleges. Driving on many city roads during the
northeast monsoon is a risky affair. In many places, roads with potholes are
proving to be a major obstacle course.
According to weather
reports, many places in Tamil Nadu will continue to receive rainfall on Friday
after which there will be a gradual dip in rainfall activity till November 15.
A cyclonic circulation over the Comorin area and strong easterly/northeasterly
winds will trigger rain over the State for a few more days. The low pressure
area over the east-central Arabian sea will also influence rain in the southern
and western parts of the State, according to the Regional Meteorological
Centre. Most places of north Tamil Nadu, including Chennai, may largely
experience a dry Deepavali, except for sporadic rain.
