    Weather and Climate Overview

    • Weather represents the short-term atmospheric conditions in a specific area, characterized by elements such as temperature, wind, precipitation, and cloudiness.
    • Climate is the long-term pattern of weather over an extended period, influenced by geographical factors like latitude, altitude, and insolation.

    Elements of Weather

    • Temperature: Measures how hot or cold an area is, recorded in degrees Celsius or Fahrenheit.

      • Diurnal Temperature Range: Difference between the highest and lowest temperatures in one day.
      • Annual Temperature Range: Difference between average temperatures of the hottest and coldest months.

    • Factors Influencing Temperature:

      • Latitude: Areas closer to the poles are colder; those near the equator are warmer.
      • Altitude: Temperature decreases with increasing altitude, with a normal lapse rate of 1°C per 165 meters.
      • Distance from Sea: Coastal areas have moderate temperatures; inland areas can experience extremes.
      • Direction of Winds: Winds from warm regions raise temperatures; those from cold regions lower it.
      • Ocean Currents: Warm currents increase coastal temperatures, while cold currents decrease them.

    • Precipitation: Refers to all forms of water falling from the atmosphere, including:

      • Rain: Liquid droplets measured in millimeters using rain gauges.
      • Snow: Frozen precipitation that occurs in regions below freezing.
      • Hail: Ice pellets formed from moisture and updrafts in storms.
      • Frost and Dew: Water in solid and liquid forms that occurs under specific temperature conditions.

    • Atmospheric Pressure: Weight of air pressing on the Earth's surface, measured in millibars using a barometer.

      • Low pressure often leads to cloud formation and storms, while high pressure typically indicates clear weather.

    • Wind: Air moves from high to low pressure areas, characterized by direction and speed, measured using a wind vane or anemometer.

    • Humidity: Amount of moisture in the air, with absolute humidity as total moisture and relative humidity as percentage of moisture capacity based on temperature.

    Clouds

    • Composed of water droplets formed when warm air rises and cools, leading to condensation.
    • Cloud type and formation are influenced by height, temperature, and atmospheric conditions.

    Weather Instruments

    • Thermometers: Measure temperature in Fahrenheit and Celsius.

      • Variants include mercury thermometers for high temperatures and alcohol thermometers for lower temperatures.

    • Barometers: Measure atmospheric pressure; types include mercury and aneroid barometers.

    • Hygrometers: Measure humidity using wet and dry bulb methods to calculate relative humidity.

    • Rain Gauges: Collect and measure precipitation in millimeters or centimeters.

    • Anemometers: Measure wind speed, often using rotating cups to gauge airflow.

    Isohyet and Isotherm

    • Isotherm: Lines connecting areas with the same temperature on a map.
    • Isohyet: Lines joining points of equal rainfall, depicted on isohyet maps.

    Human Impact on Climate and Weather

    • Human activities such as agriculture and industrialization can inadvertently alter weather patterns.
      • Acid Rain: Result of pollutants from industry damaging ecosystems.
      • Long-term effects of climate change due to greenhouse gas emissions include increased extreme weather conditions like droughts, floods, and severe storms.

    • Composed of water droplets formed when warm air rises and cools, leading to condensation.
    • Cloud type and formation are influenced by height, temperature, and atmospheric conditions.

    Weather Instruments

    • Thermometers: Measure temperature in Fahrenheit and Celsius.

      • Variants include mercury thermometers for high temperatures and alcohol thermometers for lower temperatures.

    • Barometers: Measure atmospheric pressure; types include mercury and aneroid barometers.

    • Hygrometers: Measure humidity using wet and dry bulb methods to calculate relative humidity.

    • Rain Gauges: Collect and measure precipitation in millimeters or centimeters.

    • Anemometers: Measure wind speed, often using rotating cups to gauge airflow.

    Isohyet and Isotherm

    • Isotherm: Lines connecting areas with the same temperature on a map.
    • Isohyet: Lines joining points of equal rainfall, depicted on isohyet maps.

    Human Impact on Climate and Weather

    • Human activities such as agriculture and industrialization can inadvertently alter weather patterns.
      • Acid Rain: Result of pollutants from industry damaging ecosystems.
      • Long-term effects of climate change due to greenhouse gas emissions include increased extreme weather conditions like droughts, floods, and severe storms.

    Weather and Climate Overview

    • Weather represents the short-term atmospheric conditions in a specific area, characterized by elements such as temperature, wind, precipitation, and cloudiness.
    • Climate is the long-term pattern of weather over an extended period, influenced by geographical factors like latitude, altitude, and insolation.

    Elements of Weather

    • Temperature: Measures how hot or cold an area is, recorded in degrees Celsius or Fahrenheit.

      • Diurnal Temperature Range: Difference between the highest and lowest temperatures in one day.
      • Annual Temperature Range: Difference between average temperatures of the hottest and coldest months.

    • Factors Influencing Temperature:

      • Latitude: Areas closer to the poles are colder; those near the equator are warmer.
      • Altitude: Temperature decreases with increasing altitude, with a normal lapse rate of 1°C per 165 meters.
      • Distance from Sea: Coastal areas have moderate temperatures; inland areas can experience extremes.
      • Direction of Winds: Winds from warm regions raise temperatures; those from cold regions lower it.
      • Ocean Currents: Warm currents increase coastal temperatures, while cold currents decrease them.

    • Precipitation: Refers to all forms of water falling from the atmosphere, including:

      • Rain: Liquid droplets measured in millimeters using rain gauges.
      • Snow: Frozen precipitation that occurs in regions below freezing.
      • Hail: Ice pellets formed from moisture and updrafts in storms.
      • Frost and Dew: Water in solid and liquid forms that occurs under specific temperature conditions.

    • Atmospheric Pressure: Weight of air pressing on the Earth's surface, measured in millibars using a barometer.

      • Low pressure often leads to cloud formation and storms, while high pressure typically indicates clear weather.

    • Wind: Air moves from high to low pressure areas, characterized by direction and speed, measured using a wind vane or anemometer.

    • Humidity: Amount of moisture in the air, with absolute humidity as total moisture and relative humidity as percentage of moisture capacity based on temperature.
