Extreme Weather on Earth

Q: How much do you know about the extreme weather on Earth? Brainstorm the students with a list of words and phrases related to the weather. Write the answer on the board. Next, you are asked to classify the list into logical categories such as weather type, weather measurement tool, weather influence.

Ask students to see the extreme weather photo gallery and watch the video about the weather. Extreme weather to display photo gallery. Ask each volunteer to read each title aloud. Next, we display the geographical video "Weather 101" nationwide. Let the students explain the events of extreme weather. Question: What are the conditions necessary for each weather event? The following student reactions are caused. Difference in circulating air quantity, collision of warm air quantity and cold air quantity (forefront), and jet. Q: What are the factors that affect bad weather? It causes the student reactions such as: solar (temperature), water (precipitation), and other atmospheric conditions such as rapids, atmospheric pressure, wind, humidity, clouds

A copy of the weather forecast on the worksheet will be distributed to each student. Check the answers provided with the instructions aloud. Allow students to gather and organize information we know about weather conditions and atmospheric conditions for each weather. Their answer is as follows.

Q: What is the climate? How is the climate related to the weather? Some students understand that the climate near the equator has a lower climate than regions far from extreme. In a short period of time we confirm that students understand that the term "weather" represents the state of the atmosphere. The term climate represents a pattern of weather for a particular region over an extended period of time, usually over 30 years. The climate is the average weather pattern for a specific area. Build the background using the following example. The weather in Wisconsin State varies from day to day. One day may be very warm, such as a recordable temperature with temperatures exceeding 100 degrees Fahrenheit (F) and other summers not even reaching 70 degrees Fahrenheit. Temperatures in winter may change. However, the climate is a long-term trend. The temperature trend in the Midwest is data collected from 1895 to 2006, indicating that the overall temperature is between 0.3 ° F and 8 ° F.

Worldwide, our climate has undergone fundamental changes, such as changes in average weather conditions and frequency of extreme weather events. Most noteworthy is that the Earth's climate system is quite warm and it is highly likely that these changes are mainly the result of human activities (at least 95% of the chances). Corals inhabiting tropical coral reefs are sensitive to heat and can only withstand a narrow temperature range. However, climate change has resulted in abnormally high sea surface temperatures, resulting in summer coral bleaching (see below). As the temperature rises, the strength of coral bleaching increases.

During the interglacial period, the Earth generally enjoyed a relatively stable weather pattern, and the expansion of biodiversity and vegetation ecosystem also increased significantly. It is changing. Extreme weather fluctuations, melting of glaciers and polar ice, large amounts of methane from ocean cage sediments, large amounts of carbon dioxide and methane from the world's tundra decompose and release gases. We can expect more and more intense and frequent heat waves, storms, floods, droughts, sea level rise, flooded cities, arctic swirls, forest fires and crop failures

Global warming is a continuous rise in the surface temperature of the earth, which is the effect on climate conditions. Global warming has an adverse effect on the Earth's atmosphere. It causes extreme weather conditions, which in turn adversely affect life on the planet. Global warming caused by emission of greenhouse gases such as carbon and methane has brought about adverse effects such as sea level rise, increase in air pollution, extreme weather conditions, etc. in various areas.
