1960 North Indian Ocean Cyclone Season
The 1960 North Indian Ocean cyclone season featured two deadly tropical cyclones that killed approximately 20,000 people collectively in East Pakistan (present-day Bangladesh). The Indian subcontinent divides the North Indian Ocean into two areas: the Bay of Bengal to the east and the Arabian Sea to the west. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. On average, five storms form in the North Indian Ocean every season with dual peaks in activity during May and November. Cyclones that occurred between 45°E and 100°E were included in seasonal records by the IMD. Fifteen depressions developed during the 1960 season, with five becoming cyclonic storms. The majority of the activity took place in the Bay of Bengal, where eleven systems formed; however, the season's first storm formed over the Arabian Sea on May 10. The st ...

1940s North Indian Ocean Cyclone Seasons
The years between 1940 and 1949 featured the 1940s North Indian Ocean cyclone seasons. Each season was an ongoing event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Below are the most significant cyclones in the time period. Because much of the North Indian coastline is near sea level and prone to flooding, these cyclones can easily kill many with storm surge and flooding. These cyclones are among the deadliest on earth in terms of numbers killed. On 27 April 1949, India Meteorological Department (IMD) became a member of the World Meteorological Organization after independence of India, independence. 1940 season *May 17–25, 1940 – A severe cyclonic storm existed over the Bay of Bengal. *June 23–27, 1940 – A cyclo ...

1970 Bhola Cyclone
The 1970 Bhola cyclone (Also known as the Great Cyclone of 1970) was a devastating tropical cyclone that struck East Pakistan (present-day Bangladesh) and India's West Bengal on November 11, 1970. It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest natural disasters. At least 300,000 people lost their lives in the storm, possibly as many as 500,000, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. Bhola was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season. The cyclone formed over the central Bay of Bengal on November 8 and traveled northward, intensifying as it did so. It reached its peak with winds of on November 10, and made landfall on the coast of East Pakistan on the following afternoon. The storm surge devastated many of the offshore islands, wiping out villages and destroying crops throughout the region. In the most severely affected upazila, ...

Landfall
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there. Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as friction with the ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area.

Cyclone Chapala
Extremely Severe Cyclonic Storm Chapala was a powerful tropical cyclone that caused moderate damage in Somalia and Yemen during November 2015. Chapala was the third named storm of the 2015 North Indian Ocean cyclone season. It developed as a depression on 28 October off western India, and strengthened a day later into a cyclonic storm. Chapala then rapidly intensified amid favorable conditions. On 30 October, the India Meteorological Department (IMD) estimated that Chapala attained peak three-minute sustained winds of . The American-based Joint Typhoon Warning Center (JTWC) estimated sustained winds of , making Chapala among the strongest cyclones on record in the Arabian Sea. After peak intensity, Chapala skirted the Yemeni island of Socotra on 1 November, becoming the first hurricane-force storm there since 1922. High winds and heavy rainfall resulted in an island-wide power outage, and severe damage was compounded by Cyclone Megh, which struck Yemen a week ...

South Yemen
South Yemen ( ar, اليمن الجنوبي, al-Yaman al-Janubiyy), officially the People's Democratic Republic of Yemen (, ), also referred to as Democratic Yemen (, ) or Yemen (Aden) (, ), was a communist state that existed from 1967 to 1990 as a state in the Middle East in the southern and eastern provinces of the present-day Republic of Yemen, including the island of Socotra. South Yemen's origins can be traced to 1874 with the creation of the British Colony of Aden and the Aden Protectorate, which consisted of two-thirds of the present-day Yemen. Prior to 1937 what was to become the Colony of Aden had been governed as a part of British India, originally as the Aden Settlement subordinate to the Bombay Presidency and then as a Chief Commissioner's province. After the collapse of Aden Protectorate, a state of emergency was declared in 1963, when the National Liberation Front (NLF) and the Front for the Liberation of Occupied South Yemen (FLOSY) rebelled against the Bri ...

Barometer
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is 1013 hPa (mbar). Etymology The word ''barometer'' is derived from the Ancient Greek (), meaning "weight", and (), meaning "measure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mbar
The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, who was a founder of the modern practice of weather forecasting. The International System of Units, despite previously mentioning the bar, now omits any mention of it.. The bar has been legally recognised in countries of the European Union since 2004.British Standard BS 350:2004 ''Conversion Factors for Units''. The US National Institute of Standards and Technology (NIST) deprecates its use except for "limited use in meteorology" and lists it as one of several units that "must not be introduced ...
