Contour line future weather patterns. Isobars are commonly used in television weather reporting. Isallobars are lines joining points of equal pressure change during a specific time interval. These can be divided into "anallobars", lines joining points of equal pressure increase during a specific time interval, and "katallobars", lines joining points of equal pressure decrease. In general, weather systems move along an axis joining high and low isallobaric centers. Isallobaric gradients are important components of the wind as they increase or decrease the geostrophic wind. An isopycnal is a line of constant density. An "isoheight" or "isohypse" is a line of constant geopotential
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
