WebSPC forecasters examine winds, relative humidity, and the potential for thunderstorms with little to no rain — so-called dry thunderstorms — across the continental United States. We categorize areas as having elevated, critical, or extremely critical fire weather risk , and identify locations where isolated and scattered dry thunderstorms may occur. Winds at higher altitudes become steadier, more persistent, and of higher velocity. Because power available in wind increases as the cube of velocity (the velocity-cubed law), assuming other parameters remaining the same, doubling a wind's velocity gives 2 =8 times the power; tripling the velocity gives 3 =27 times the available power. With steadier and more predictable winds, high-altitude wind has an advantage over wind near the ground. Being able to locate HAWP to effecti…

In 1947, Norwegian explorer Thor Hyerdahl and a small crew used trade winds to travel from the coast of Peru to the coral reefs of French Polynesia, more than 6,920 kilometers (4,300 miles), in a sail-powered raft. The expedition, named after the raft (Kon-Tiki) aimed to prove that ancient mariners could have … Ver mais The boundary between these two areas is called a front. The complex relationships between fronts cause different types of wind and weather patterns. Ver mais Prevailing winds are winds that blow from a single direction over a specific area of the Earth. Areas where prevailing winds meet are called convergence zones. Generally, prevailing winds blow east-west rather than north … Ver mais Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles. Polar … Ver mais The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. The horse latitudes are a narrow zone of warm, dry climates between westerlies and the trade winds. … Ver mais WebHá 1 dia · When gases warm up, the atoms and molecules move faster, spread out, and … diabetic living apple with pie
