- 1. UnderstandingtheWeather Weather shapes our world and daily lives. This presentation explores how we measure weather conditions and use predictions to prepare for various weather events. "A change in the weather is sufficient to create the world and oneself anew." - Marcel Proust, French novelist by sandeep swamy
- 2. TheBigQuestions 1 Measurement&Monitoring How can we measure and monitor the weather around us? 2 PracticalApplications How do weather predictions help us prepare for events like heavy rain, storms, drought and heat waves?
- 3. Weathervs.Climate Weather Short-term atmospheric conditions. Changes hour to hour, day to day. Includes temperature, humidity, precipitation, wind, and cloud cover. Climate Long-term weather patterns in a specific area. Measured over decades. Determines ecosystems, agriculture, and human settlement patterns.
- 4. WeatherMeasurementTools Thermometer Measures air temperature in degrees Celsius or Fahrenheit. Anemometer Measures wind speed and direction. RainGauge Measures precipitation amount in millimeters or inches. Barometer Measures atmospheric pressure to predict weather changes.
- 5. ModernWeatherMonitoring WeatherStations Automated systems collecting data 24/7 from thousands of locations worldwide. WeatherSatellites Provide global coverage, tracking cloud patterns, storms, and atmospheric conditions. WeatherRadar Detects precipitation, estimates intensity, and tracks movement of storms. WeatherBuoys Floating stations monitoring marine weather conditions in oceans and lakes.
- 6. WeatherForecastingMethods AI&MachineLearning Advanced pattern recognition improving forecast accuracy ComputerModels Numerical weather prediction using supercomputers HistoricalAnalysis Comparing current conditions with past weather events DataCollection Gathering measurements from global monitoring networks

- 8. PreparingforHeavyRain MonitorForecasts Check reliable weather sources daily during rainy seasons. SecureProperty Clear drains, secure outdoor items, and check for leaks. PlanTravel Avoid flood-prone routes and allow extra travel time. EmergencyKit Prepare supplies including flashlights, batteries, and drinking water.
- 9. StormPreparation StayInformed Monitor weather alerts through multiple channels. SecureHome Reinforce windows, trim trees, and secure loose objects. PowerOutagePlan Prepare alternative lighting, charging, and cooking methods. EmergencyResponse Know evacuation routes and emergency contact information.
- 10. DroughtManagement WaterConservation Implement household and agricultural water-saving practices. Drought-ResistantPlanting Use native and drought-tolerant plant species. WaterStorage Collect and store rainwater during wet periods. WaterRecycling Reuse greywater for appropriate purposes.
- 11. HeatWaveSafety StayCool Use air conditioning, fans, and cool showers. StayHydrated Drink plenty of water, even when not thirsty. LimitExposure Avoid outdoor activities during peak heat hours.
- 12. Weather'sImpactonAgriculture Weather predictions help farmers plan planting, irrigation, and harvesting. Advance warnings allow protective measures against frost, floods, and drought.
- 13. WeatherandTransportation AirTravel Weather forecasts help airlines reroute flights and prevent delays. Pilots use weather data to navigate safely. MaritimeTransport Ships rely on weather predictions to plot safe courses. Ports prepare for storms by securing vessels. RoadTransport Road crews prepare for snow, ice, and flooding. Travelers adjust plans based on weather alerts.
- 14. Weather-RelatedDisasters 20K+ AnnualDeaths Global weather-related disaster fatalities $165B EconomicImpact Average annual cost of weather disasters 4X FrequencyIncrease Growth in extreme weather events since 1970s
- 15. EarlyWarningSystems Detection Satellites and sensors identify developing weather threats. Analysis Meteorologists assess data and predict impact. AlertDistribution Warnings sent through multiple channels to public. ResponseActivation Emergency services prepare and implement action plans.
- 16. WeatherAppsandServices MobileApps Real-time updates and personalized alerts. TVForecasts Visual presentations with expert analysis. WeatherWebsites Detailed maps and comprehensive data. RadioUpdates Accessible alerts during power outages.
- 17. WeatherandPublicHealth Weather Event Health Risks Preventive Measures Heat Waves Heat stroke, dehydration Cooling centers, hydration campaigns Cold Snaps Hypothermia, frostbite Warming shelters, winter clothing drives Heavy Rain Waterborne diseases Water purification, drainage improvements Air Stagnation Respiratory issues Air quality alerts, reduced outdoor activity
- 18. TraditionalWeatherPrediction AnimalBehavior Observing changes in animal activity to predict weather shifts. Birds flying low before storms Frogs croaking more before rain PlantIndicators Using plant responses as weather forecasting tools. Pinecones opening in dry weather Flowers closing before rain SkyObservations Reading cloud patterns and colors to predict conditions. "Red sky at night, sailor's delight" Ring around moon indicating precipitation
- 19. FutureofWeatherForecasting AIIntegration Machine learning improving prediction accuracy. HyperlocalForecasts Block-by-block predictions through dense sensor networks. ExtendedTimelines Reliable forecasts weeks or months in advance. PersonalizedAlerts Custom warnings based on individual needs and activities.
- 20. KeyTakeaways MeasurementMatters Accurate weather monitoring requires diverse tools and technologies. PredictionPower Forecasts help us prepare for and mitigate weather-related risks. CommunityResilience Weather knowledge builds safer, more prepared communities. GlobalImportance Understanding weather connects us to our environment and each other.
