UNIT SUMMARY
Since the time of their early existence, humans have migrated to regions of the Earth that offer climates favorable to their survival and have planned to persevere extreme weather events. In this unit, students will observe models and analyze data to learn how the interplay between atmospheric variables such as temperature, air pressure, and moisture leads to the typical and sometimes extreme weather events that humans’ experience. Analyzing weather data to make predictions is a key part of this unit and students’ understanding of how weather patterns can help us predict future weather events. This unit aims at explaining how Earth’s tilt, along with its changing position around the Sun causes variation in the amount of incoming solar radiation (insolation) that reaches the surface. This unequal distribution of energy causes variations in seasons we experience on Earth. Students also will learn that climate is influenced by latitude, proximity to large bodies of water, ocean currents, among other factors.

Rain yesterday, sunshine today and snow tomorrow -- what causes the weather we experience day-to-day?
Atmospheric moisture, temperature and pressure distributions; jet streams, wind; air masses and frontal boundaries; and the movement of cyclonic systems and associated tornadoes,
In this paper, I will discuss what tornadoes are and how they form, what different forms of tornadoes there are, what tornado watches and warning are and give examples of tornadoes in Oklahoma and what destruction they caused, also while providing information about the Doppler radar.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009,
So the warm moist air creates clouds of rain and thunderstorm. Adding to that winds with different speed going in different directions assisting in expanding these great clouds of rain and thunderstorm. With
Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).
The weather in a story has a big effect on the reader. Weather in a story is veryimportant; it helps readers visualize a scan or setting for better visitation of thebook. When reading a book the more details the book has the better you canunderstand what your reading. When a book describes weather details this helps areader picture the mood of the story. Weather details give off an emotionalconnection to the story such as “dark stormy night” makes you think of a scary storyor something bad happening. A book reading “a bright sunny day” it makes youthink of a nice summer day and a happy setting. Weather has a strong influence on areader and is a vital part of a
Global climate change has and will continue to have a dramatic impact on the frequency of when tornadoes will form. Climate change has and will make the earth’s conditions more favorable for these formations. As the climate warms up and moisture on the ground rises, it will become a main factor in the establishment of tornados. The probability of more moisture formation in the increasingly warmer atmosphere can lead to more frequent formations of life-threatening precipitation incidents. Global warming will also allow weather patterns and climate changes to occur in other places, which could lead to tornado formation in areas where they have never occurred. The conditions that favor tornado outbreaks could shift and expand elsewhere. The impacts
Severe storms in coastal regions are really a potential natural hazard to citizens live near the beaches. Although they can enjoy the beautiful sight around the sea, the storms that occurred randomly definitely became a jeopardize that damages buildings and causing death of human beings. Australia had many severe storms in the past few years. For example the constant storms in Hunters Valley, and the storms in Sydney almost every year.
It is astonishing how many calculations and work goes into determining the weather each day. Meteorologists read this information and broadcast it to households every night. The weather each day helps determine a region’s climate, but the climate does not determine the weather every day. Meteorology is one of the studies of the atmosphere, and the daily weather helps determine the climate. These are all common terms to most people, but each term carries more meaning than most intend to realize.
QLCSs are organized lines of convection that commonly occur over portions of the United States (Trapp et al. 2005), and can produce all forms of severe weather, including hail, strong straight-line winds, and occasionally can spawn tornadoes (Smith et al. 2012). Trapp et al. (2005) found that about 18% of all tornadoes in the US are associated with QLCSs. The development of the QLCS is dependent upon the storm produced cold pool and the environmental shear. As the line of storms propagates, rain-cooled air descends from the downdraft to the surface and spreads
Meteorology, when compared to other sciences like Physics, Mathematics, and Astronomy, is a relatively new area of study. Most advancement in meteorological technology has occurred within about the last hundred years, and because of its relatively recent development, there has not been an adequate amount of research in the subject. The science has advanced enough to now issue weather watches and warnings, including severe thunderstorm, tornado, flood, and other types. However, in the past these severe weather warnings have been highly inaccurate and unreliable, and most tornado warnings in previous years have allowed for almost no time to get to safety. Tornadoes are some of the most dangerous natural disasters to occur, and it is crucial that
Researchers believe that these Increasing tornado outbreaks are being caused by climate change. They believe it is climate change because have seen changes in the Meteorological quantities. This has to do with the atmospheric phenomena and weather of a region. Although they saw these change they found that these trends are increasing fastest for the most extremum outbreaks. Modelling studies have projected that CAPE will increase in a warmer clime lead to more frequent environs favorable to severe electrical storm in the U.S. However, they found that the meteorological course was not due to increasing CAPE but instead due to trends in storm congenator helicity, which has not been projected to increase under clime change.
Over the years there has been a lot of controversy on if climate change is an issue that needs to be discussed and solved. There is a constant debate among scientist on if human actions are contributing the changing of earth’s climates. Climate change is defined as the change in average weather patterns for a specific region or Earth as a whole. This could include the change in an average temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference between weather and climate is the period of time specific patterns are recorded. Weather patterns are looked at over a much shorter period of time, meaning that these patterns are going to be more sporadic and change more frequently. Climate on the other had is recorded over a much longer period of time and usually show less drastic changes in patterns when compared to weather. Some people may argue that climate change is not an issue because Earth’s temperature is always changing do to natural effects. What people don’t realize is that human activity has effected the rate that earth’s temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar, 2015).
The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.
Modern tornado predicting for the past hundred years has been haphazard at best. The National Weather Service has invested a great sum of money into research, but the results have been sporadic. Although tornado fatalities have declined by 93% from 1925 data, the tornado warning time still does not prevent all fatalities (Brotzge and Donner, 1715). Weather patterns change rapidly during a severe weather outbreak, but meteorologists look for common indicators of tornadic activity. Relying on Doppler radar and other weather
Climate change is a global or regional change in typical weather conditions. Although Earth’s climate has changed in the past, studies show that in the last 100 years global average temperatures have increased by more than 1°F (Dunbar). These seemingly small changes can have tremendous implications such as rising sea levels, decrease in ice cover, and change in precipitation patterns. As an extended consequence, extreme weather events are anticipated to become altered as well. The Tri-State tornado of 1925 crossed three state lines causing billions in damage and killing hundreds; it was the deadliest tornadoes in U.S. history. It is difficult to determine whether the tornado was altered by climate change. However, we can theorize about the possible effects of climate change on tornadoes in general to gain insight on future outcomes.
