Weather symbols are used to indicate different conditions of weather such as fog, snow, rain and are usually used for weather forecasting. The first commercial weather map was put out by the U.S. weather bureau in 1910. The icons we know emerged in the 1970s. The symbols can also convey intensity. For example, a single dot represents rain, and multiple dots represent heavy rain. Alt code is a simple way to insert different weather symbols in the text. For example, the sun symbol in a text could mean summer; it may also indicate the warmth. Cloud with rain symbol indicate rainy weather; it may have the symbolic meaning of crying.
