Weather map motion. Two-dimensional streamlines based on wind speeds at various levels show areas of convergence and divergence in the wind field, which are helpful in determining the location of features within the wind pattern. A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated into symbols and plotted on these maps along with other meteorological data that are included in synoptic reports sent by professionally trained observers. The use of weather charts in a modern sense began in the middle portion of the
What if chart (Red) decides the outcome when crossed with recessive color gene (yellow) producing a hybrid (Red*) flower. If either parent possesses the dominant gene, the table shows the outcome that results. What if chart A what if chart (Whif chart, WHIF analysis, etc.) is a visual tool for modeling the outcome of a combination of different factors. The table can represent actual results or predicted outcome based on combinations of parameters. It is a visual equivalent of asking the question, "what if...?" or 'what happens if...?' multiple times for each and every factor being considered. What if charts are also used
