The red lines with semicircular points are called hot fronts, while the blue lines with triangular points are called cold fronts. During the 1920s, a group of Scandinavian meteorologists, known collectively as the Bergen School, developed the concept of representing the atmosphere in terms of air masses. Media. When both the lines meet at particular areas, they form a stationary front; these are boundaries that do not show much movements, and are represented by alternating points of both front types. This usually tells us about the approach of a storm. There are many different factors which could influence someone's experience of the weather, including the temperature, wind speed, cloud coverage, humidity, chance of rain, visibility and . Observations are measurements of meteorological quantities such as temperature, rainfall, pressure, wind and humidity. The isobars (lines joining equal air pressure areas) and related weather fronts are shown spread across the United States. When a cold front overcomes a hot one, it is represented by a purple line, with both rounded and triangular points oriented in the same direction. A triangular barb indicates a speed of 50 knots. Skip to content Toggle navigation. There are two types of observation site, Standard and Non standard. The speed represents the average wind speed expected at that time, i.e. Convection is the movement within a liquid or gas driven by differences in temperature. Therefore, temperature is clearly a vital part of getting an overall picture of the predicted atmospheric conditions. This convergence line can give hours of persistent precipitation over very localised areas, whilst a few miles down the road it is relatively dry, leading to some heavy snowfall/rainfall. If a line is originating from the south straight upwards, it means that the wind is flowing in the northern direction. Download 1,128 free Weather icons.
