    Study Notes

    Weather Data Importance

    • Accurate weather data is crucial for predictions and various applications.

    Problems with Long-Term Forecasts

    • Data accuracy and availability are critical factors in weather forecasting.
    • Current technologies lack regular, comprehensive measurements of the lower and middle atmosphere.

    Data from Earth's Surface - Temperature & Air Pressure

    • Thermometers measure temperature using Fahrenheit or Celsius scales.
    • Barometers measure air pressure.

    Data from Earth's Surface - Wind Speed & Relative Humidity

    • Anemometers measure wind speed.
    • Hygrometers measure relative humidity.

    Data from Earth's Surface - Automated Surface Observing System (ASOS)

    • The ASOS collects data consistently, providing critical weather data for aviation, forecasting, and research.
    • ASOS data is gathered 24/7.
    • Different types of weather stations are used within the ASOS network.

    Data from the Upper Atmosphere

    • Radiosondes gather upper-atmosphere data (temperature, pressure, humidity).

    Weather Observation Systems - Weather Radar

    • Weather radar systems track specific locations of precipitation.
    • Doppler effect analysis helps determine the speed of precipitation movement.

    Weather Observation Systems - Weather Satellites

    • Some satellites use infrared imagery for night observations.
    • Infrared imagery maps cloud cover and surface temperatures.
    • Water-vapor imagery aids in weather analysis.

    Surface Weather Analysis - Station Models

    • Station models are weather data records for a specific site and time.
    • Meteorological symbols represent data.
    • Isobars are lines of equal pressure, while isotherms are lines of equal temperature.

    Types of Forecasts - Digital Forecasts

    • Digital forecasts utilize physical principles and mathematics to predict atmospheric variables over time.

    Types of Forecasts - Analog Forecasts

    • Analog forecasts compare current weather patterns to similar past patterns.

    Short-Term Forecasts

    • Short-term forecasts are more accurate than long-term forecasts due to greater system change variability.

    Long-Term Forecasts

    • Long-term forecasts are less reliable because computers cannot model all affecting variables.

    Chaos Theory & The Butterfly Effect

    • Chaos theory explains the sensitivity of weather systems to initial conditions.
    • The butterfly effect illustrates how small changes can have large consequences in weather patterns.

    Lab Procedure - To Much Heat & Pressure

    • Instruction to conduct lab procedure is given in the text regarding heat and pressure using a flashlight to measure.
