One of the most simplest signs, wind currents, are represented as lines drawn with long or short extensions called barbs. If sun and rain droplets are shown together, it means that rain is precipitating along with low-intensity sunlight. For example, if the fog symbol of three horizontal, parallel lines is drawn in front of the sun weather symbol, one can interpret it as being partly foggy or fog with mild sunlight. One more characteristic of these signs is that they can be combined with various other basic symbols that depict weather. This usually tells us about the approach of a storm. 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. They can move in a forward and backward direction every day, with all the points showing more or less similar intensity. 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. The warm fronts are represented by curved red-colored lines with rounded/semi-circular points, which are oriented towards the wind current direction. The latter is characterized by decreasing pressure of air which is lifted upwards.Ī cold front is represented by a blue-colored curved line with triangular points, which indicate the direction of the wind currents. The former is characterized by atmospheric air under increasing pressure which sinks towards the land surface. A high pressure area is denoted by ‘H’ in blue, whereas, a low pressure area is denoted by ‘L’ in red. These are also called front line boundaries, and they represent the line of separation between hot and cold air masses which are present in either high or low pressure areas.
The following image illustrates the main symbols which are used in describing the weather of a particular region. The type and number of symbols are decided depending on the kind of weather of the region where the readings are taken.

These values are then processed and interpreted by meteorologists using latest software programs, and conclusions are drawn using this data to prepare weather maps. In the field of meteorology, readings and values of various atmospheric parameters are taken at specific intervals around the globe at weather stations. The same type of graphical map representations are now digitally made, using real-time data. For instance, Tropical Storm and Hurricane use the same icon as Thunderstorms.Considered as a class of important tools used by meteorologists, weather maps and associated symbols were manually drawn in the past. Note that some icons are used for multiple weather conditions. Close enough that you should be able to find a match if you are unsure what an icon means. However, the following set comes very close. But none exactly match the ones used on the iPhone. Yahoo has many different sets of weather icons for use on their sites and by third-party developers. Not only is there not a guide, but it seems the icons used in the iPhone app are not used anywhere else. So you would think that there would be a guide somewhere to these icons.
A bright yellow sun means “sunny.” But others are less obvious. But the iPhone Weather app doesn’t include descriptions of the graphic icons that appear next to each day. The forecast should be the same as if you want to Yahoo and looked up the weather for your area. A common question people have is “What does this icon mean in the iPhone Weather app?” The iPhone Weather app gets its information from Yahoo Weather.
