2I. Weather Observations Meteorologist – person who studies weatherTake measurements & interpret dataUse data from Doppler radar, satellites, and weather balloons to make weather predictionsMake weather maps to make weather forecasts
3II. Forecasting Weather When meteorologists make a forecast, they are using the basic science process skills of prediction & communicationa. Station model – shows weather conditions at a specific location on Earth’s surface and are used to forecast weatherb. Weather maps have lines that connects equal temperature or pressure1. Isotherm – lines that connect equal temperature2. Isobar – lines that connect equal air pressurea. When isobar lines are close together, pressure difference is large between areasb. When isobar lines are far apart, pressure difference is small between areas
