PREAMBLE:
From 1st April 2010 the Visakhapatnam weather was of the Summer Heat and gradually spurred to high temperatures. Luckily the weather at the Coastal region of Maharanipeta to Bheemilipatnam was one of a cool winds and the summer heat was not felt that much either on the roads or inside the homes excepting Apartment dwellings of huge complexes. The hot summer sun was felt of course, by many a people at Visakhapatnam city and in the several wards of GVMC and even the beach coast exhibited on the 11th April 2010, a wide scenario of colours.

Exceptionally noteworthy is the Yellowish shades of the beach sands. Deep blue colour of the sea is a proof of the varied constituents of the rough Bay of Bengal Sea

12th April 2010
A new sunspot (provisionally numbered AR1062) is rapidly emerging in the sun's southern hemisphere. GEOMAGNETIC STORM: A coronal mass ejection hit Earth's magnetic field at approximately 12:30 UT on April 11th. The impact sparked a G2-class geomagnetic storm with auroras over Scandinavia, Scotland, Canada and northern-tier US states such as Maine, Michigan and Wisconsin. Vertical rays of green light shot as high as 20o above the horizon," says McKenna. The interplanetary magnetic field (IMF) near Earth is pointing south, an orientation that favours strong geomagnetic activity. High-latitude sky watchers should remain alert for auroras tonight. For the first time this year, geomagnetic storm ignited auroras over the continental United States. "The lights were bright enough to produce a reflection from the surface of Lake Superior," says photographer Shawn Malone, who recorded the scene from a beach in Marquette, Michigan:

A new sunspot has rapidly emerged at the circled location. The biggest prominence in years has leapt off the surface of the sun and on Saturday, April 11th, 2010 a coronal mass ejection (CME) hit Earth's magnetic field. The impact caused a G2-class geomagnetic storm and, for the first time this year, ignited auroras over the continental United States. There are no large coronal holes on the Earth-facing side of the sun on 12th April 2010.
The combined effect of the Prominence and the Coronal Mass Ejection by the Sun and the piled ash debris to a height of 11km of the Iceland’s volcano has drastically changed the Earth’s Atmosphere.
Devastating Super-Rain:
Three states in India Bihar, Bengal and Assam experienced a super-rain on the mid-night of Tuesday, the 13th April, 2010. It was accompanied by windy-gales of 125km/hr that destroyed several thousands of houses uprooted poles, trees and road, bridge and railway communication systems. More than 200 people died and several were injured. Bihar kishanganja, supala, purnia districts were affected. Assam Dhubri district and capital city of Bengal viz. Kolkata and north Dinajapur district were also devastated by the winds and heavy rain.
Andhra Pradesh:
Karimnagar bore the brunt of Heat Wave summer resulting in the death of 12 people. of age group 16-35. While the windy-gales lashed the Kaddaph district kamalpuram mandalam, Chittoor district kvpalle mandalam. Thunderbolts killed one old lady Nagamma (65yrs) in gajulapalli. The Monday, Tuesday and Wednesday 12th, 13th And 14th instants of April, 2010 the windy-gales were very destructive. Kurnool last all its Beetelnut (tamalapakula) crop worth Rs.80 lacks. Rajampeta, rachitic, pulivendala, badwale there was loss of Boppai, banana, mango crops. In Nellore and Prakasam districts the heavy rain with windy-gales destroyed the crops. Boykonda gangamma temple tower damaged by a thunderbolt and scattered away the idols erected on the
Temple dome. Nearly 20feet lengthy faults were formed on the temple tower structure. Also the Madanapalli Lord Venketeswara temple (pillar). Dwajastambba collapsed. 2000 acres of tobacco etc crops were destroyed.

The Iceland's volcano:
The Iceland's volcano has spewed about 140 million cubic metres of ash over the past three days, into the air from Eyjafjallajokull volcano and was blown across northern Europe, Icelandic scientists have said on the 19th April 2010 at 10:00AM. The Icelandic volcanologists said most of the ejected material was fine-grained airborne tephra, but 30 million cubic metres of material was deposited around the volcano vent and another 10 million cubic metres in the glacial lagoon of Gigjokulslon. They said the average magma discharge rate of 750 tonnes per second was 10-20 times greater than the average of the eruption in late March. Poland, Finland, Sweden and Netherlands have been covered with the ejected ash of the Volcano.
Its crate produced lava, which indicated that the nature of the eruption has changed. Visibility near the Eyjafjallajokull glacier was almost nil as falling ash saturated the air and covered agricultural fields with a thin layer of dust which could be dangerous to animals if eaten. The molten rock created new pathways for water to run into the crater, causing more explosions and a higher level of ash production. The column of ash rising from the volcano was as high as 11 km when it started erupting earlier last week.
Earth Quakes and Tremors:
April 17th, 2010 Saturday at 9:00AM (local time) in Tibet in Nagukya region a quake of magnitude 5.2 occurred that shook nyanrogancounty. The quake epicentre was located 60km at a depth of 10km from nayanrongacounty which is situated at 5000meters height and has very little population.
The Qinghai quake of magnitude 7.1R happened on 14th April 2010 on Wednesday morning at a depth of 10 km, which is slightly shallower than the recent Haiti quake. This area is not only on the border of Tibet. This is in the heart of the Tibetan area, the eastern Tibetan area of Kham and the Chinese authorities do recognise it as the Tibetan autonomous prefecture of Yushu, which is in present day Qinghai (85% destroyed) in eastern Tibet. That is about 800 kilometres of southwest of Xining, the provincial capital. The epicentre of the earthquake was a sparsely populated rural area about 50 kilometres west of a town called Jyeku which is the government's seat of the prefecture the provincial capital. Several dams developed cracks on the structures.
And the quake was also felt as far as away as Szechuan and Chamdo in the Tibetan autonomous area. And I think not only has the loss of life been devastating, but also the impact on Tibetan religious life, cultural life, a famous 13th Century monastery in the area was completely destroyed. Also, 25 monks there were killed and some more are missing, so it is a very bleak picture indeed. The impact on Tibetan religious life, cultural life, a famous 13th Century monastery in the area was completely destroyed. Also, 25 monks there were killed and some more are missing, so it is a very bleak picture indeed. The dead Buddhists were cremated under Vedic chanting. Eighteen after -shocks made the relief operations as dangerous.
The Sichuan next to Qinghai province earthquake (epicentre Yushu) of magnitude 7.9R in China, in May 2008 was caused by a "thrust" movement, this latest event was a "strike-slip" event, which involves sideways movement along a fault. "India bumped into Asia (millions of years ago) and threw up the Tibetan plateau. That high ground is now being squeezed out towards the east and down towards the south-east.

(UKPA) – 7 hours ago of 19th April 2010 Seven die as quake hits Afghanistan:
A magnitude 5.3 earthquake struck in mountains north of Afghanistan's capital early on Monday 19th April 2010, killing at least seven people and injuring 30, officials said. The quake hit just before 1am (2030 GMT on Sunday 18th April 2010) in Samangan province, between Kabul and the northern city of Mazar-i-Sharif, according to the province's deputy governor, Kulam Sakhi Baghlani.The quake was felt in Kabul as well as the neighbouring countries of Uzbekistan and Tajikistan. Roads and communications are sparse in the area, and casualty reports take time to reach authorities.Baghlani said three districts of scattered mud-walled villages were affected, with more than 300 homes damaged and dozens of head of livestock killed. Landslides sparked by the quake had blocked roads, making even more arduous what was already an eight-hour drive along winding mountain trails from the provincial capital of Aybak."The quake would have been felt much more intensely up in the mountains," Baghlani said. He said three civil defence units had been dispatched to check on the damage and casualties.
The 21st April 2010 thunderstorm:

There was a low depression formation near to the coast of Visakhapatnam and the cloud & thunder without any shower occurred around 2.00Pm to 4.00PM on the 21st April 2010. But the 21st April 2010 thunderstorm of cumulus nimbus clouds devastated about 1.20lack acres of farm and crop lands spread over 9 districts of Andhra Pradesh, by the wind, gales and the hailstones. This has just happened within a few hours of time in the mid-afternoon of 21st April 2010.
23rd April 2010 onwards the Visakhapatnam weather has again became one of a sweltering summer heat and the people were afraid to walk during the mid-day on the roads. Luckily the effect of low-depression that has fizzled out left some cool breeze occasionally that provided relaxation to the sweating public. It drizzled for just 2 minutes at 19:19PM on the 25th April 2010.
And the above images of the Western Sky taken on the 26th April 2010 remarkably shows the Air-Glows of the dust and fine ash matter filled Earth’s Equatorial atmosphere. Shri Ramprasad of MVD High School Physical Science Teacher has remarked that even the ancient people have poetical documented the colour appearance of the sky in terms of Red and Yellow hues as that in mythology of Goddess Parvathi sprinkling her dress material water colours to drape the enchanting beauty of the sky.
CONCLUSION:
The weather in Southern Peninsular India and especially at Visakhapatnam that city, which hasn’t received any thunder storm to-date, offered a fine observable polluted sky and the Ionosphere to grasp some of the Global environmental effects in the Atmosphere.Visakhapatnam City has not received any rain during the month of April 2010 in spite of the expected super-rains in the tropical hot regions of Andhra Pradesh.
