25.3 Weather Instruments Winds are always labeled from the direction from which they blow. Wind vane – most common, located on buildings; always point into the wind. Anemometer – measures wind speed and direction

Weather Balloons Measuring Upper - Atmospheric conditions Doppler RADAR Radio wave pulses Particles of water bounce back Weather Satellites

El Niño and La Niña New Text p El Niño - Normally cold offshore waters are replaced by unusually strong warm equatorial waters (Read p. 546) El Niña – atmospheric phenomenon when surface temperatures of the eastern Pacific are colder than average; blows cold air over the Pacific NW & plains, but warms the rest of the U.S. Normal conditions

25.4 Forecasting the Weather How to read weather maps:

Isobars Iso = equal Bar = pressure Pressure flows ‘around’ the pressure center counter clockwise around lows clockwise around highs The closer the isobars, the stronger the winds

Low pressure system: Increased clouds, winds, Chance of rain High pressure system: Clear calm conditions with reduced chance of rain. Drier air results in greater range of H and L temps.
