  • WHAT IS METEOROLOGY? Meteorology Is the Science of Weather
    WHAT IS METEOROLOGY? Meteorology is the science of weather. It is essentially an inter-disciplinary science because the atmosphere, land and ocean constitute an integrated system. The three basic aspects of meteorology are observation, understanding and prediction of weather. There are many kinds of routine meteorological observations. Some of them are made with simple instruments like the thermometer for measuring temperature or the anemometer for recording wind speed. The observing techniques have become increasingly complex in recent years and satellites have now made it possible to monitor the weather globally. Countries around the world exchange the weather observations through fast telecommunications channels. These are plotted on weather charts and analysed by professional meteorologists at forecasting centres. Weather forecasts are then made with the help of modern computers and supercomputers. Weather information and forecasts are of vital importance to many activities like agriculture, aviation, shipping, fisheries, tourism, defence, industrial projects, water management and disaster mitigation. Recent advances in satellite and computer technology have led to significant progress in meteorology. Our knowledge of the weather is, however, still incomplete. WHAT IS SYNOPTIC METEOROLOGY? Weather observations, taken on the ground or on ships, and in the upper atmosphere with the help of balloon soundings, represent the state of the atmosphere at a given time. When the data are plotted on a weather map, we get a synoptic view of the worlds weather. Hence day-to-day analysis and forecasting of weather has come to be known as synoptic meteorology. It is the study of the movement of low pressure areas, air masses, fronts, and other weather systems like depressions and tropical cyclones.

Yadav Physical features of Himalayas and Neighbourhood Climatological Characteristics of Himalayas Complex Terrain and a variety of climates : Beauty of the Himalayan region. It prevents cold, dry Arctic northerly winds blowing into the subcontinent, which keeps South Asia much warmer than corresponding temperature regions in the other continents. The mountain ranges also influence mid latitude systems ( WD , STJ ), resulting in snow in Western Himalayas and rainfall for parts of northern India. There is a large variation in the annual average precipitation in the Himalayas. The southern slopes of Eastern Himalayas experience some of the highest annual rainfall totals on Earth while other areas receive as low as 50 mm a year. Rainfall decreases from east to west. Common Natural Hazards Western Himalayas (Heavy snowfall, avalanche, flash flood, cloud burst, earthquake…) Central Himalayas (Heavy snowfall, heavy rainfall, Landslide, avalanche, cloud burst, earthquake…. ) Eastern Himalayas (Thunderstorm, heavy rainfall, Landslide, earthquake ) Summer climate Winter climate North Atlantic Oscillation (NAO) NAO The North Atlantic Oscillation (NAO) is a climatic phenomenon in North Atlantic Ocean of fluctuations in the difference of atmospheric pressure at sea level between the Icelandic low and the Azores high. The NAO is the dominant mode of winter climate variability in the North Atlantic region ranging from central North America to Europe and much into Northern Asia. The NAO is a large scale seesaw in atmospheric mass between the subtropical high and the polar low. The corresponding index varies from year to year, but also exhibits a tendency to remain in one phase for intervals lasting several years.

Hunt,a* Andrew G. Turnera,b and Len C. Shaffreyb aDepartment of Meteorology, University of Reading, UK bNCAS–Climate, University of Reading, UK *Correspondence to: K. M. R. Hunt, Department of Meteorology, University of Reading, Earley Gate, PO Box 243, Reading RG6 6BB, UK. E-mail: [email protected] Western disturbances (WDs) are upper-level synoptic-scale systems embedded in the subtropical westerly jet stream (STWJ), often associated with extreme rainfall events in north India and Pakistan during boreal winter. Here, a tracking algorithm is applied to the upper-tropospheric vorticity field for 37 years of ERA-Interim reanalysis data, giving a catalogue of over 3000 events. These events are analysed in a composite framework: the vertical structure is explored across a large number of dynamic and thermodynamic fields, revealing a significant northwestward tilt with height, strong ascent ahead of the centre, which sits above the maximum surface precipitation, and a warm-over-cold, dry-over-moist structure, among other signatures of strong baroclinicity. Evolution of the structures of cloud cover and vertical wind speed are investigated as the composite WD passes across northern India. Cloud cover in particular is found to be particularly sensitive to the presence of the Himalayan foothills, with a significant maximum at 300 hPa approximately 1 day after the WD reaches peak intensity. k-means clustering is used to classify WDs according to both dynamical structure and precipitation footprint and the relationship between the two sets of WDs is explored.

  • A Case Study on Dust Storms/Thunderstorms Over Uttar Pradesh on 2 May 2018
    VayuMandal 45(2), 2019 A Case Study on Dust Storms/Thunderstorms over Uttar Pradesh on 2nd May 2018 J. P. Gupta1, A. H. Warsi1, R. P. Kuril1 1India Meteorological Department, Meteorological Centre, Lucknow Email: [email protected] ABSTRACT Thunderstorms are the manifestation of the convective activity in the atmosphere. It’s destructive off springs are the hailstorms, lightening, high winds, heavy rains and most violent of all are the tornadoes. Dry thunderstorms produce dust storms which are usually considered to be natural hazards. During such events, dust aerosol is loaded into the atmosphere, directly reducing visibility and effectively reflecting solar radiation back to space. Essential conditions for the formation of a severe thunderstorm are (i) Conditional instability (ii)Availability of moist air at lower levels (iii)Insolation and orography for initial lifting of moist air at higher levels (iv)Presence of high lapse rate of temperature, due to dry westerly at upper levels and moist southerly/southwesterly air at lower levels and (v)Presence of trough or cyclonic circulation in lower levels over the region. In addition, strong vertical wind shear is found to be one of the important factors for the occurrence of severe thunderstorm as the release of latent energy in an environment of strong vertical wind shear often leads to the development of severe convective storms. Though each one of the above mentioned conditions is considered favourable for convective development, their relative importance and the weightage to be given to each factor have not yet been clearly established. Thus, any discussion on this will have to be only qualitative and in general terms.

  • CLIMATE 1. What Is Meant by Western Disturbance? the Cyclonic
    CLASS 12 - GEOGRAPHY CHAPTER – CLIMATE 1. What is meant by Western disturbance? The cyclonic depressions which originate over the Mediterranean Sea and travel eastwards across Iran and Pakistan. These winds ultimately bring rainfall and weather disturbance to the northern part of India. 2. What are the two characteristics features of the tropical climate? High temperature round the year and rainfall in the afternoon. 3. Explain with two examples the role played by mountain ranges in the distribution of rainfall in India during the south West monsoon period. The south West monsoon is dashing against the Himalaya and causing heavy rainfall in the north eastern hilly states area. The south West monsoon is dashing against the Western Ghats causing heavy rainfall in the windward side of the mountain. 4. What are the western disturbances? The system of pressure and wind is disturbed as a result of the inflow of depressions from the west and the north west are called western disturbances. 5. The north west plains of India experience winter rainfall. Explain the statement with reason. The north west plains of India consisting of Punjab, Haryana, Rajasthan and western Uttar Pradesh receive some winter rainfall which is caused due to the invasion of western disturbances. 6. What is co-efficient of variation? Explain with examples. The large variations in actual amount of rainfall is expressed in terms of co-efficient of variation (CV). The CV of annual rainfall in India generally ranges between 15 %to 30%. Of the west coast have a CV lower than 15 %. The variability increases from the west into the interior of the plateau as well as from Orissa and West Bengal towards the north and North West.

  • WESTERN DISTURBANCES Gursharn Singh (M.SC
    WESTERN DISTURBANCES Gursharn Singh (M.SC. GEOGRAPHY,M.A. ENGLISH) Department of geography, University of Jammu,( India) Western Disturbances are low-pressure areas embedded in the Westerlies, the planetary winds that blow from west to east between 30 and 60° latitude. They originate in the Mediterranean region, travel westward and enter India loaded with moisture, where the Himalayas obstruct them, causing rain and snow over northern India. The moisture in these storms usually originates over the Mediterranean sea and Atlantic Ocean. WDs are important to the development of the Rabi crop in the northern subcontinent. The frequency of western disturbance amplified because of presence of easterlies from Bay of Bengal. Also due to pronounced warming over the Tibetan plateau in recent decades which can be attributed to climatic warming, favours enhancement of meridional temperature gradients. The warming in recent decades over west central Asia led to an increase in instability of the western winds thereby increasing WDs leading to a higher intensity for heavy precipitation. Such disturbances can damage crops resulting into economic as well as agricultural loss for the people and farmers. Farm output is affected when crops that are ready to be harvested or about to ripen, get soaked in excessive rainfall. This is a concern in states like Madhya Pradesh, Gujarat, Maharashtra and Rajasthan, Punjab and Haryana. I.INTRODUCTION Western disturbances are low-pressure areas embedded in the Westerlies, the planetary winds that flow from west to east between 30°-60° latitude. They usually bring mild rain during January-February, which is beneficial to the rabi crop.
