Bad Clouds. 1. Introduction | World of Weather. Introduction When defensive football coaches study game films of an upcoming opponent, they look for tendencies in the formations and plays used by the opposing team’s offense. By recognizing such patterns, defensive coaches can design strategies to predict the play the opposition will run on any given down. In similar fashion, weather forecasters look for patterns on weather maps in order to predict the tendencies of potentially offensive weather. Such pattern recognition can play an instrumental role in short-term forecasts (one to three days ahead), medium-range forecasts (four to ten days) or long-range outlooks (months to seasons). This pattern of steering winds around the Bermuda high and a trough over the Midwest favors a tropical cyclone moving northward up the Atlantic Coast. For an example of pattern recognition, suppose it’s mid-September, the heart of Atlantic hurricane season. A classic set-up for an outbreak of severe weather during the spring.
Golden Gate Weather Service Weather Calculator. Life Cycle of a Thunderstorm. The storm has considerable depth, often reaching 40,000 to 60,000 feet (12 to 18 km). Strong updrafts and downdrafts coexist. This is the most dangerous stage when large hail, damaging winds, and flash flooding may occur. NWS JetStream Max - Hydrologic Cycle Diagram. Press quality poster English | Spanish (26" x 36" - 6 mb pdf) Evaporation is the change of state of water (a liquid) to water vapor (a gas). On average, about 47 inches (120 cm) is evaporated into the atmosphere from the ocean each year.Transpiration is evaporation of liquid water from plants and trees into the atmosphere.
Nearly all (99%) of all water that enters the roots transpires into the atmosphere.Sublimation is the process where ice and snow (a solid) changes into water vapor (a gas) without moving through the liquid phase.Condensation is the process where water back into a water droplets (a liquid). This is when we begin to see clouds.Transportation is the movement of solid, liquid and gaseous water through the atmosphere. Without this movement, the water evaporated over the ocean would not precipitate over land.Precipitation is water that falls to the earth.
