2009 North Indian Ocean Cyclone Season
The 2009 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ''ARB'' by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated ''BOB'' by the IMD. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. The tropical cyclone scale for this ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Aila
Severe Cyclonic Storm Aila (JTWC designation: 02B) was the second named tropical cyclone of the 2009 North Indian Ocean cyclone season. Warned by both the Regional Specialized Meteorological Center (RMSC) and Joint Typhoon Warning Center (JTWC), Aila formed over a disturbance over the Bay of Bengal on May 23, 2009 and started to intensify and organize reaching sustained wind speeds of 110 kmh (70 mph). It was the worst natural disaster to affect Bangladesh since Cyclone Sidr in November 2007. A relatively strong tropical cyclone, it caused extensive damage in India and Bangladesh. The storm was responsible for at least 4 deaths across Bangladesh and India; more than 1 million people were left homeless. Health officials in Bangladesh confirmed a deadly outbreak of diarrhea on 29 May, with more than 7,000 people being infected and four dying. In Bangladesh, an estimated 20 million people were at risk of post-disaster diseases due to Aila. Meteorological history Late on ...

Cyclone Bijli
Cyclonic Storm Bijli (Joint Typhoon Warning Center, JTWC designation: ''01B''), was the first tropical cyclone to form during the 2009 North Indian Ocean cyclone season. Bijli formed from an area of Low Pressure on April 14. Later that evening, RSMC New Delhi upgraded the low-pressure area to a Depression and designated it as BOB 01. The Joint Typhoon Warning Center (JTWC) then issued a Tropical Cyclone Formation Alert for the system and soon after designated it as Tropical Depression 01B. On the evening of April 15, both RSMC New Delhi and the JTWC reported that the system had intensified into a tropical storm, with the former naming it Bilji. Soon after, Bilji reached its peak intensity as it approached the coast of Bangladesh. However, on the morning of April 17, Bijli weakened to a deep depression due to land interaction, before making landfall just south of Chittagong. The remnants of Bilji continued to weaken as they tracked across northern Myanmar, before RSMC New Delhi issu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chandabali
Chandabali (or Chandbali) is an old town in the Bhadrak district of Odisha on the bank of the River Baitarani. History Before the 19th century AD, Chandabali was a small fishing village, and a natural river port. In 1866, trading began from this port to Bengal and in 1881, it was declared a government port by the British government. This led to growth and development of a market for agricultural produce. In the 1910s, the United States Hydrographic Office noted that the opening of the Bengal-Nagpur Railway had drawn trade away from the port, and that the port was now considered to be simply part of the port of Dhamra. At the time, the port had between 22 and 30 feet of anchorage, in front of the town, with three landing piers, the water 10 feet deep at their ends. A steamer service ran four times per week between there and Calcutta. The town itself had a single police station, a customhouse and warehouse, and a traveler's bungalow. The 1901 Census of India had recorded the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-pressure Area
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation. The strongest high-pressure areas result from masses of cold air which spread out from polar regions into cool neighboring regions. These highs weaken once they extend out over warmer bodies of water. Weaker—but more frequently occurring—are high-pressure areas caused by atmospheric subsidence: Air becomes cool enough to precipitate out its water vapor, and large masses of cooler, drier air descend from above. Within high-pressure areas, winds flow from where the pressure is highest, at the center of the area, toward the periphery where the pressure is lower. However, if the planet is rotating, the straight direction of the air flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Formation Alert
A Tropical Cyclone Formation Alert (TCFA) is a bulletin released by the U.S. Navy-operated Joint Typhoon Warning Center in Honolulu, Hawaii or the Fleet Weather Center in Norfolk, Virginia, warning of the possibility of a tropical cyclone forming from a tropical disturbance that has been monitored. Such alerts are generally always issued when it is fairly certain that a tropical cyclone will form and are not always released before cyclone genesis, particularly if the cyclone appears suddenly. The TCFA consists of several different checks that are performed by the on-duty meteorologist of the system and its surroundings. If the condition being checked is met, a certain number of points are given to the system. Parts of the TCFA Section 1 The first section of the TCFA contains information on the area of the alert as well as the estimated center of the circulation. The estimated maximum sustained winds are provided as well. Section 2 The second section generally contains more specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Delhi, India
New Delhi (, , ''Naī Dillī'') is the capital of India and a part of the National Capital Territory of Delhi (NCT). New Delhi is the seat of all three branches of the government of India, hosting the Rashtrapati Bhavan, Parliament House, and the Supreme Court of India. New Delhi is a municipality within the NCT, administered by the NDMC, which covers mostly Lutyens' Delhi and a few adjacent areas. The municipal area is part of a larger administrative district, the New Delhi district. Although colloquially ''Delhi'' and ''New Delhi'' are used interchangeably to refer to the National Capital Territory of Delhi, both are distinct entities, with both the municipality and the New Delhi district forming a relatively small part of the megacity of Delhi. The National Capital Region is a much larger entity comprising the entire NCT along with adjoining districts in neighbouring states, including Ghaziabad, Noida, Gurgaon and Faridabad.

Rainband
A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure. Rainbands within tropical cyclones are curved in orientation. Rainbands of tropical cyclones contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes. Rainbands associated with cold fronts can be warped by mountain barriers perpendicular to the front's orientation due to the formation of a low-level barrier jet. Bands of thunderstorms can form with sea breeze and land breeze boundaries, if enough moisture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
