Teleconnection patterns Essay Example for Free

Teleconnection patterns Essay1. Explain how observed teleconnection patterns bear help in the zeal of a seasonal abide forecast.So the simple way of explaining a teleconnection is a warmer and storage tank pacific cornerstone influence rainfall. we saw how a vast warming (El Nio) or chill (La Nia) of the equatorial tropical Pacific can affect the weather in different regions of the mankind (Ahrens, 2015, p.271). These major storms as we learned in earlier chapters affect people in many regions of the world. A seasonal forecast is very important because it gives people a chance to prepargon for what could possibly be. Forecasters can give a prediction of a wetter or drier season. They sport said that this suit of forecasting has been seen to be very keen in this field of work. If we can predict weather patterns for the coming(prenominal) months will only prevail for regions abroad. This will only prepare us for the worst and hope for the best. 2. If the temporary worker erature is dropping and the dew transmit is holding steady, what is your forecast for the relative humidity? Explain your answer.Lets first actualise what a dew point is. The dew point is basically the temperature at which the if it cools to a certain temp you will get hundred percent relative humidity. If the dew point drops showtime enough the cold gentle wind wont be capable of holding the moisture. If the temperature is dropping and you have a stable dew point I would predict a higher amount of relative humidity. The lower the dew point dropped is when you decrease in relative humidity. If you had a hot summer day and a steady dew point you would actually had a lower relative humidity. 3. In what ways are severe boomstorms different from ordinary cell thunderstorms? What are some of the meteorological or atmospheric conditions that favor the schooling of severe thunderstorms?The basics of a thunder storm are fairly easy, because they consist of thunder, lightning, winds, r ain and heavy hail at times. The storm itself whitethorn be a single cumulonimbus cloud, or several thunderstorms may mental strain into a meet (Ahrens, 2015, p.288). Thunderstorms form in unstable environments with warm air. They are known as convective storms. Cell thunderstorms form in regions where limited vertical wind shear is present. The winds directionor speeds do not abruptly modification rapidly. Ordinary storms develop and mature through a cycle, as cell thunderstorms dont have this development. Different conditions vary from warm air rising, random turbulent eddies and terrain. These are a few that can be a trigger to these more impactful storms.4. Where do thunderstorms form just about frequently in the US? Why is this the case? Is this also where most tornadoes total? Explain.The most area that gets thunderstorms more frequently is the disjunction Coast. This area includes all of Florida, to include parts of Georgia, Alabama, Mississippi and Louisiana. We also f ind that, in summer on the Gulf Coast, a thick layer of warm, moist air extends upward from the surface (Ahrens, 2015, p.303). This also makes a point that more storms consuming Hail are located in the Great Plains. Thunderstorms typically form more in the tropical latitude, which makes the gulf coast a prime location.The two areas that tornados occur most is the cranny Alley and the Dixie Alley. Tornado Alley stretches from Central Texas to Nebraska, as Dixie Alley all over Mississippi to Alabama. The Central Plains region is most susceptible to tornadoes because it often provides the proper atmospheric setting for the development of the severe thunderstorms that spawn tornadoes (Ahrens, 2015, p.313). This area gets that humid dry air with a cold layer to stick with which creates the perfect formula for a unstable environment. This makes Spring a high frequency for tornados and winter the low time for them to occur.5. The region of greatest tornado activity shifts northward fro m early spring to summer. Why does this occur?This is really interesting because the peak for tornados is actually around June 12th. This makes early spring a probability in the midst of 25-60 percent. When you hit June the probability jumps through the roof to 90 percent. The biggest possibility for the shift is El Nino, but in that location is not an actual confirmation on why this shift happens. The next possibility is the warming weather moving north is shifting the peak period by 7-10 days. This making Dixie Alley and Tornado Alley more susceptible to tornados during that peak time.
