This document discusses various weather phenomena like winds, storms, cyclones and extreme weather conditions. It provides examples of weather events that cause weather conditions and lists some common weather events. There are activities that describe cyclones like Cyclone Amphan, explain what to do during earthquakes, thunderstorms and cyclones. It also discusses tools used to measure weather like radar, anemometer, wind vane and barometer. The document talks about weather forecasting apps like AccuWeather and factors they mention in predictions. It provides information on the Indian Meteorological Department and technologies used in weather forecasting like satellites, supercomputers and Doppler radar.
Physics Wind , Storms and Cyclone's ppt
- 3. Wind – Moving air is called wind. • Cyclones – A large scale air mass that rotates around • a strong centre of low atmospheric pressure. Storms – They are a powerful disturbance of the Atmosphere
- 5. Weather Condition VS. Weather Event •A current Weather Condition is caused by a Weather Event which took place in the past. •In other words Weather Event causes the Weather Condition. •For Example – It has been raining since 2 days and now there is a flood. •Here raining is a weather event that has caused the flood which is the weather condition
- 6. S.No. Weather Event Elements Present 1. Thunderstorm Rain, Clouds, Lightning, Thunder, Wind 2. Snowstorm Clouds, Snow, Chilly Wind 3. Cyclone Rainbands, Eye, Eyewall 4. Hail Hailstones
- 8. CYCLONES
- 13. • Cyclone Amphan • 16 May 2020 – 21 May 2020 • Super Cyclonic Storm Amphan was a powerful and catastrophic tropical cyclone that caused widespread damage in Eastern India, specifically West Bengal, and also Bangladesh in May 2020. Highest wind speed: 260 km/h • Total fatalities: 118 • Date: 16 May 2020 – 21 May 2020 • Damage: > $13.6 billion (2020 USD); (Costliest on record in the North Indian Ocean) • Category: Category 5 Hurricane (SSHWS) • Affected areas: India, Bangladesh, Sri Lanka, Odisha, Bhutan, East India
- 14. Climate Change Is a Challenge for Sustainable Development Climate change is the most Significant challenge to achieving Sustainable Development, and it threatens to drag millions of people Into grinding poverty. Climate Change related disasters might make this very difficult as funds will be diverted to tackle climate change impacts. Urbanites might find it difficult to respond to SDG 11 which requires the establishment of sustainable cities and communities among other SDG demands.
- 18. EARTHQUAKES Stay inside Drop under heavy furniture such as a table, desk, bed or any solid furniture. Cover your head to prevent being hit by falling objects. Hold onto the Don’t go near doors as they may slam shut and cause injuries. Try to avoid windows, bookcases, tall furniture and light fixtures as the glass might shatter. Don’t stay in

- 20. CYCLONES
- 21. Measuring Weather with Tools ACTIVITY 4
- 22. Accuweather • Accuweather is an app which tells us the accurate weather forecast for each day. • It is available on smart phones, tablets, wired and mobile internet sites, and smart TVs. AccuWeather produces local weather videos each day for use on their own website, on the Local AccuWeather Channel, on wired Internet and mobile application and websites. The mobile application has a minute-by-minute forecast and also collects crowd-sourced weather observations.
- 23. STEPS TO USE ACCUWEATHER You can also extend the additional data for a particular day. To see the 15- day forecast, tap on “Forecast.” The home screen displays the current weather. Allow the app to use your current location. Download the app and accept its terms and conditions.
- 25. RADAR A RADAR is used to measure cyclones. Radar works by transmitting pulses of energy and then measuring the amount of energy that is returned to the radar receiver from various forms of precipitation. It is also used to measure Hurricanes
- 26. ANEMOMETER An anemometer is a device used for measuring wind speed. It is also a common weather station instrument. The term is derived from the Greek word anemos, meaning wind.
- 27. WIND VANE It is also called weather vane or weather cock. It is used to show the direction of wind. The word vane comes from the Old English word fana, meaning 'flag'.
- 28. BAROMETER This instrument is used to measure air pressure. It can forecast short term changes in weather.
- 29. WIND MILL Windmills are used for pumping water or grinding grain. It is a structure that converts wind power into rotational energy by means of sails.
- 31. Weather Forecasting Apps • The app I have used to see the weather forecasting is AccuWeather • AccuWeather gathers the best and most comprehensive weather data to deliver forecasts with Superior Accuracy. • Some other apps are Dark Sky, Google forecast, NOAA, Weather Bug, Weather Wiz, Weather underground, Weather channel etc.
- 32. Factors Mentioned While Showing Predictions Topic Factors Highest temperature this month 28’ Celsius Lowest temperature this month 7’ Celsius Wind Speed 3km / hr Max Wind Gusts 6km / hr Humidity 53 % Indoor Humidity 47 % Dew Point 9’ Pressure 1016 mbar Cloud Cover 0% Visibility 6 km Cloud Ceiling None
- 33. The Indian Meteorological Department is an agency of the Ministry of Earth. Sciences of the Government of India. It is the principal agency responsible for meteorological observations, weather forecasting, prepare weather reports and seismology (the study of earthquakes). It has the responsibility for forecasting, naming and distribution of warnings for tropical cyclones in the Northern Indian Ocean region. Meteorologists are able to predict the changes in weather patterns by using several different tools. For example, weather balloons are special balloons that have a weather pack on them that measures temperature, air pressure, wind speed, and wind direction in all the layers of the troposphere.
- 34. Technologies used in weather forecasting AWIPS Automated surface – observing systems Doppler Radar Radiosondes Satellite Data Supercomputers
- 35. Meteorological Satellites of India Meteorological satellites can provide an alternative means of obtaining weather data to drive ecosystem models. Meteorological satellites have either continuous or daily global coverage, but they are often limited in their spatial resolution as a result of the high altitude of their orbits. Meteorological satellites see more than clouds: city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, energy flows. GSAT - 18
- 36. Weather Forecasting tools used in real life scenario • Scenario 1 = Planning Picnics • When we plan an outdoor picnic we ensure that the weather is pleasant and it is not raining.
- 37. Weather Forecasting tools used in real life scenario • Scenario 2 = Planning Trips • When we plan a trip we wish to go somewhere warm and pleasant so that it is the perfect weather for a trip. • For that we have to check the weather forecast.
