Easy Mind MapsPrecipitation refers to water falling from clouds in forms like rain, snow, sleet, and hail. It significantly influences the water cycle, climate, and agriculture. Different types include rain (drizzle, showers, continuous), snow, sleet, hail, and freezing rain, each with unique characteristics and examples worldwide. Understanding these types is essential for weather prediction.
Fog is a dense cloud of water droplets reducing visibility to less than 1 km, while mist has greater visibility. Haze consists of dry particles causing reduced clarity. Smog combines fog with pollution, leading to severe health risks. Understanding these phenomena aids in weather prediction and pollution control, crucial for safety and health.
What is Humidity? 🌧️💧 Types of Humidity 1. Absolute Humidity (AH) 🌡️ 2. Specific Humidity (SH) 🌍 3. Relative Humidity (RH) 🌫️ Factors Affecting Humidity ✅ Temperature – Warmer air holds more moisture, increasing humidity.✅ Altitude – Higher altitudes have lower humidity due to thinner air.✅ Air Pressure – Low-pressure areas increase humidity, high-pressure areas […]
Water exists in three states: solid (ice), liquid (water), and gas (water vapor), depending on temperature and pressure. Heat exchange processes, including melting, freezing, evaporation, condensation, sublimation, and deposition, drive weather and influence climate. Understanding these processes is vital for geography and exam preparation, regulating Earth’s climate and weather patterns.
What are Winds? 🌬️ Factors Affecting Winds 1. Pressure Gradient Force (PGF) 🔄 2. Coriolis Effect 🌍 3. Friction with Land & Water 🌊 Types of Winds A. Planetary (Permanent) Winds 🌎 These winds blow constantly throughout the year and are influenced by the Earth’s pressure belts. Wind Type Direction Latitude Example Trade Winds (Easterlies) […]
Atmospheric pressure is the force exerted by air on Earth’s surface, measured in millibars or Pascals. It varies with altitude, temperature, humidity, and Earth’s rotation, influencing weather systems. High-pressure areas bring clear skies, while low-pressure zones cause storms. Understanding atmospheric pressure is essential for meteorology and weather forecasting.
Temperature inversion occurs when air temperature increases with altitude, trapping colder air below. This phenomenon impacts weather, leading to fog and smog, especially in winter in regions like North India. Types include radiation, advection, frontal, and subsidence inversions, each with distinct effects on air quality and climate.
What is Temperature Distribution? 🌡️ Factors Affecting Temperature Distribution 1. Latitude (Distance from the Equator) 📍 ✅ High Temperature → Near the Equator (0° latitude).❄ Low Temperature → Near the Poles (90° latitude). 2. Altitude (Height Above Sea Level) 🏔️ ✅ Plains are warmer → Lower altitude.❄ Mountains are colder → Higher altitude. 3. Distance […]
The heat budget is the equilibrium between incoming solar radiation and outgoing terrestrial radiation, crucial for maintaining Earth’s temperature and climate stability. It involves absorption, reflection, and the greenhouse effect. Imbalances lead to global warming and severe climate changes, influenced by factors like latitude and greenhouse gas concentrations.
The atmosphere, a gas layer surrounding Earth, is essential for sustaining life by providing oxygen and regulating temperature. It consists mainly of nitrogen and oxygen, with various layers serving distinct functions. Key issues include the greenhouse effect and ozone depletion, which pose environmental challenges requiring urgent action for sustainability.
