You will then use weather station data to analyze current atmospheric conditions, identify fronts and weather patterns, and forecast future weather patterns. Today meteorologists often use computer programs to draw isolines. Weather observations are taken synoptically, which means that they are taken at the same time around the world. One Draw isotherms on the map using the blue pen. Where is it raining, snowing, windy, hot or humid? More than just plots of raw weather reports, you can analyze maps to highlight key features Answer to 1. Once station models are on the map, we draw lines such as isobars (equal Meteorologists use the station plots to draw lines of constant pressure (isobars), temperature (isotherms), and dew point (isodrosotherms) to achieve an understanding of the current state of the atmosphere. Draw your isotherm in a neat and smooth line instead of a jagged line. Globally, the standard unit for measuring rainfall is the millimeter. . The 500-millibar surface is a constant pressure surface approximately midway up in the troposphere (the Before trying to locate a cold front, we needed to draw in a few isobars and map out the pressure pattern. Remember, like isobars, these lines (called isotherms) are smooth and do not cross each other. Remember, like isobars, these lines (called isodrosotherms) are draw lines of constant pressure (isobars), temperature (isotherms), and dewpoint (isodrosotherms) to achieve an understanding of the current state of the atmosphere. Here we will con- struct some manually to better understand them.
