1. Explain how observed teleconnection patterns can help in the preparation of a seasonal weather forecast. So the simple way of explaining a teleconnection is a warmer and cooler pacific can influence rainfall. “we saw how a vast warming (El Niño) or cooling (La Niña) of the equatorial tropical Pacific can affect the weather in different regions of the world” (Ahrens‚ 2015‚ p.271). These major storms as we learned in earlier chapters affect people in many regions of the world. A seasonal forecast

really big hurricanes can span 1‚127 kilometers. The size of a hurricane is not directly related to its wind speed or force. Small ones can be extremely strong‚ while big ones can be relatively mild. The spiraling winds of the most powerful tornados can reach a speed of about 320 miles per hour‚ the most violent winds on earth. This is faster than airplanes could fly‚ faster than a formula one race car‚ and almost half the speed of sound. However‚ most tornadoes range at less than 200 miles

What’s the weather like? Windy! 1. Windy systems are produced by two fundamental forces: the heat of the sun and the spinning of the earth. By heating the atmosphere‚ the sun affects the patterns of air pressure around the globe. Because of the earth’s position in relation to the sun‚ different parts of the atmosphere are heated more or less‚ according to the time of the year. High and low air pressure areas form and air constantly moves to reduce the former and lift up the latter. 2. The

Situation Awareness and Decision Making in a Warning Environment Advanced Warning Operations Course IC Core 2 Lesson 3: Team SA Warning Decision Training Branch Lesson 3 will focus on the Situation Awareness (SA) of teams. The “teams” in this lesson are not limited to the forecast office staff. For example‚ another team would be the entire group comprised by the forecast office‚ the media‚ and emergency managers‚ who are all part of the warning process. 1 Lesson 3: Team SA Learning
Premium Tornado Storm The A-Team
An earth quake can be described as a shaking of the Earth’s crust. It is mainly a movement of the whole crust that originates in the center of the earth. Earthquakes happen when the underlying rock suddenly shakes or breaks off. The moving of the underlying rock causes the surface rocks to slide and‚ as a result‚ leads to the earthquakes. Earthquakes can be extremely disastrous and cause a lot of damage in the place where they happen. The earthquake can happen once or happen as a series. This depends

tornadoes is found in Tornado Alley‚ USA. What is a tornado: * A vortex (whirling mass of air)descends from well developed cumulonimbus cloud. * A tornado vortex is in contact with the cloud and the ground * Violent winds (100m per second) * Extreme pressure gradients (25mb per 100m) and air rushing from the high to low causes the spinning winds. (Hurricanes 20mb per 100km!!) * Diameter of funnel is rarely more then 200m Key conditions required for a tornado to form: *
