During summer and spring, the weather pattern is commonly hot and dry. During this pattern of weather, people try to stay cool by using the air conditioning or going for a swim.
During winter, the weather pattern is cold, and temperatures are usually the lowest they will be all year. When the weather pattern is cold, people wear hats, sweaters, jackets, and mittens to keep warm.
During blizzards, people stay home from work and school until snow has been removed from the streets and the area is safe. If weather patterns go on for too long, they can lead to emergencies like heat waves, flooding, and blizzards.
However, this behavior is not always uniform; the usual weather pattern deviates from its typical course. Prime examples of such disruption are the El Niño (Little Boy) and La Niña (Little Girl) phenomenon.
These are opposite and unusual weather patterns that are part of a cycle known as the El Niño-Southern Oscillation (ENSO). Experts consider ENSO as a powerful climatic force that has driven ecological change, particularly in tropical forests and coral reefs.
The periodic warming of the sea can cause drought and decrease rainfall in tropical rainforests. Global warming actually amplifies the effects and duration of both El Niño and La Niña.
More serious weather, like tornados and hurricanes, can cause severe damage to people and properties. Today, we'll be learning about the different aspects of weather patterns, how they develop, and their movement across the country.
The high moisture content in the air prevents the sweat from evaporating off of our skin, which would normally keep us cool. High pressure areas bring calm, cool, sunny weather whereas low pressure areas bring warm weather, rain, and clouds.
Changes in air pressure also bring about clouds, collections of dust, and water vapor in the atmosphere. These processes bring changes in temperature and greatly influence human activity.
Air masses are categorized based on the temperature (polar or tropical) and their origin (land or marine). When two air masses collide, the fronts, or leading edges, create weather patterns like clouds, precipitation, and even tornados.
The air molecules are spread further apart, leaving more room for water vapor. The water molecules are forced out of the air and form clouds, which eventually condense and fall as precipitation.
The warm air moves slowly upward, again causing clouds and precipitation to form in the atmosphere. Weather patterns typically move from west to east based on a wind pattern called the jet stream.
The unique pattern of the jet stream is driven by the rotation of the earth. The warm air condenses in the cold, upper atmosphere causing clouds and rain.
The air eventually stops rising and spreads north and south towards the Earth's poles. It’s been the stuff of science fiction for generations: a time machine that would allow researchers to reach back into yesteryear and ask new questions about long-ago events.
Air masses are thousands of feet thick and extend across large areas of the Earth. Jet streams The local weather conditions that we experience at the Earth's surface are related to these air masses and fronts.
High in the atmosphere, narrow bands of strong wind, such as the jet streams, steer weather systems and transfer heat and moisture around the globe. Coriolis effect As they travel across the Earth, air masses and global winds do not move in straight lines.
Similar to a person trying to walk straight across a spinning Merry-Go-Round, winds get deflected from a straight-line path as they blow across the rotating Earth. This motion can result in large circulating weather systems, as air blows away from or into a high or low pressure offsite link area.
EDUCATION CONNECTION Students should understand that weather events that they experience do not just occur at random but are dependent upon scientific principles and processes. The clouds, temperature, precipitation, winds and storms that you and your students observe are dependent on interactions between global systems and your local conditions such as geography, latitude, moisture levels and solar energy absorption.
By This packet is perfect for the little learners to practice their sequencing skill by completing the patterns. Students can also practice their fine motor skills by cutting and pasting.

Every time you are about to leave the house for outdoor activities, you check the weather forecast first. It is as simple as opening an app on your phone or tuning in to the weather channel on your TV.
Many variables is why we see the 14-day weather forecast change so frequently. Other tools include satellite imagery and radar to see where precipitation is.
The meteorologist takes past and present information to help predict that future weather pattern A weather radar is a handy tool for now casting as it can predict how heavy the rain and wind is based on its echo.
An echo or echo-top is a radar that determines the top of an area of precipitation. The higher the cloud, the stronger the updraft, which is the speed in which wind is traveling upwards in a storm.
Large updrafts in a storm make more significant wind gusts and hail likely. All this real-time information makes it essential to now cast as sometimes thunderstorms are so severe it requires an immediate reaction from the public.
From airplanes in the sky trying to land and take off in fog, or cargo ships avoiding large storms out on the ocean, we are continually looking at the weather.
