ABSTRACT

The cloud cluster of a wide variety has been found to form and moves away from the coastal region of Visakhapatnam early in the mornings. The weather scenario at Visakhapatnam is one of continually changing cloud structures that are infused with material content from both the solar winds and the earth tremors.

INTRODUCTION:

March 2011 end showers:

On the Saturday 26th March 2011 there was slight drizzle of rains in North Telengana covering Nizamabad, Karimanagar, Khammam, Adilabad, Mahbhoobnagar and Hyderabad with the low depression moving towards the East. Temperatures fell down by 4to 5 degrees centigrade. The low depression affect was also felt in Srikakulum, Vijayanagaram and Visakhapatnam. Another depression which has not developed into a cyclone has been found formed near Andaman & Nicobar Islands.

Earthquake of April 1st Week:

The Earthquake that occurred on Monday 4th April 2011 was felt for 3 seconds and rocked the Delhi, Uttarkhand Dehradoon, Ninetal and other mountain regions, also Chandigad, around 5h02mPM at a magnitude of 5.4R. Mostly it was felt in the North India. Epicenter was about 130 km from Hald wani in Uttarakhand and 363 km from New Delhi. It jolted Noida, Shaijabad, Rampur, Lakhiopurberi, Meerut, Moradabad, Jaipur and Narora. The quake took place at 5:01 p.m. local time and occurred less than 8 miles below the earth's surface with 29.60 N and 80.80 E of Nepal-India border epicenter. The tremors were felt in the whole of North India including quake-prone Uttarakhand, Uttar Pradesh, Rajasthan, Chandigarh, Delhi and NCR. In Uttarakhand the quake was felt in DehraDoon, Nainital, Almora, Bageshwar, Pithoragarh, Udhamsingh Nagar and Chamoli and other parts of the hill state. Powerful quakes had hit Uttarkashi in 1991 and Chamoli eight years later in then undivided Uttar Pradesh. In Bahraich district, people came out of their houses and offices in Nanpara and Rupadiya villages located on the Indo-Nepal border. Similar reports were received from districts sharing the border with Nepal, including Siddharth Nagar, Balrampur and Maharajganj. The two units of Narora Atomic Power station in Bulandshahr district in Uttar Pradesh, which is located in the seismic zone and around 450 km from the epicenter of the quake, were safe. The quake took place at 5:01 p.m. local time and occurred less than 8 miles below the earth's surface with 29.60 N and 80.80 E of Nepal-India border epicenter. Lucknowites also felt the tremors for 30 seconds. Lucknow has been placed under Zone 3 (moderate risk zone) Faizabad Ridge: Runs in a curved manner, first east to west from Allahabad to Kanpur and then starts to bend towards the north-east towards Lucknow and carries on this direction towards the Himalayas in Nepal. The belt from Mahamayanagar, Mathura and Agra from west running parallel till Ghazipur and Chandauli in East covering entire central UP, including Mainpuri, Shahjahanpur, Lucknow, Faizabad, Basti, Pratapgarh, Gorakhpur, Azamgarh and Varanasi is under moderate earthquake damage risk zone. Delhi-Hardwar ridge trending along New Delhi to the Garhwal region. Delhi-Muzaffarnagar ridge: Trends east to west, running from New Delhi to Kathgodam and Nepal.

Weather change:

On 4th April 2011 Tirupati recorded about 41.40 C but suddenly cooled in the afternoon around 2.15PM, bringing a rain at the Puthoor and Narayanavanam villages which has damaged the mango crop and around the same time the Araku Valley in Andhra Pradesh received a gentle shower wetting the ground enough for the vegetable crops and the standing crops. On Tuesday April 5th 2011 the coastal Andhra Pradesh has been warned of a likely cyclone with thunder showers. On Tuesday the Vijayanagaram on the evening had experienced gale winds and a heavy shower. In the Jiyammavalasa mandalam, Pippalabhadhra village four students felt the brunt of a thunder stroke in the mango garden two died on the spot while two survived the shock. Congo had a disaster of Fokker plane UN peace keeping aero plane crash due to heavy rains near Kansas airport, with just one survivor. Indian government banned import of food items from Japan for about three month’s time due to the radioactive contamination of the food products by the recent tsunami-nuclear disaster.

OUR OBSERVATIONS:

It’s almost certain that the earthquakes are preceded by heavy dust formations near the equatorial belt of the terrestrial atmosphere. Especially Visakhapatnam has been found quite sensitive in the formation of these clouds. The initial impact of these clouds is a rise of temperature by at least 4 to 5 degree centigrade and as well with a sharp rise in night temperatures.

The clouds assembled on the morning of March 27th, 2011 have brought in showers to the Visakhapatnam district. Temperatures fell down by 4 to 5 degrees centigrade. The low depression affect was also felt in Srikakulum, Vijayanagaram and Visakhapatnam. This certainly was a sudden change of weather preceding the Earthquake of 4th April 2011 at Nepal India border.

The Moon spectrum shows much red irradiance relative to the terrestrial early morning atmosphere. The inter distance between the Moon and the earth has more predominant red dispersion. This may be due to the outflow of solar winds with fine particulate matter. We cannot ascertain the composition of the atmosphere near Visakhapatnam due to the continuous and new induction of infused material into the lower levels.

The cloud cluster of a wide variety has been found to form and moves away from the coastal region of Visakhapatnam early in the mornings.

CONCLUSIONS: The weather scenario at Visakhapatnam is one of continually changing cloud structures that are infused with material content from both the solar winds and the earth tremors.
