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.
