Breathing Skies


By Ranger Steve Mueller

 

Warm south winds brought a record high temperature to the region in late December followed by cold air being sucked in from the northwest. By early in the new year warm air was again sweeping the area. The landscape breathes in and out creating varied weather daily.

Each breath is a temporary sigh creating different air mass movements depending on where the air is drawn from. Imagine a giant head looking in a new direction when it inhales its great breath of air. When looking north, it draws air from the north. When looking west, draws air across Lake Michigan picking up more moisture. When looking south, it brings an upwelling of warmer air from the balmy south.

Weather forecasters provide a better and more accurate account for how air masses move. They illustrate the locations of high and low pressure centers with explanations for how they interact to create changing weather.

A couple centuries ago when communication was not instantaneous, predicting weather for the next week was nearly impossible. People kept records of annual occurrences and predicted climatic expectations. It was obvious that winter would provide cold conditions compared with summer warmth.

Astronomers studied sun, Earth, moon, and star movement relationships. They determined the Earth traveled around the sun instead of the sun going around the Earth. Accumulated data gradually was pieced together to provide improved understanding for how air masses move on Earth.

Air movement has significant life and death impact on our lives. To our benefit, weather forecasters caution us about what to expect so we can plan safe travel. We are warned about hazardous driving conditions so we will adjust commute time or make decisions about cancelling school and community events.

Animals are in the dark ages when it comes to knowing what weather is headed toward their nature niche three days hence. They are locked into their own built in “Farmer’s Almanac” for climatic conditions. Climate is the long-term average of weather that occurs for any day, week, month, or year. Evolutionary adjustments in behavior and genetics allow species to survive. Some migrate, some hibernate, some stay active in winter.

Rabbits remain active all winter, warblers migrate to warm climates, and woodchucks hibernate using adaptations developed in response to long-term climate conditions. Survival is not assured because weather conditions bring extreme variations compared with averages that determine climate. A recent cold winter caused the Great Lakes to have 90 percent ice cover and many ducks were forced to small areas of open water where food was depleted. Massive duck die off occurred that year in response to weather.

When weather shifts the average conditions to colder or warmer, it is an indication that climate is changing. Climate change has occurred throughout the 5-billion-year history of Earth. Most often the average change has been slow and allowed organisms to adjust through life and death changes in behavior and genetics selection.

Some animal perceptions are keener than those possessed by humans. Changes in barometric pressure are noticed by animals and they respond before we recognize weather is about to change dramatically. Animals are attributed with responding to severe storms before they arrive while people have not taken notice. People have taken warnings from pets or wild animal behavior that resulted in saved lives.

Changing weather conditions are more easily observed than climate change. We are likely to adjust behavior for things like icy road weather. When it comes changing behavior for long-term averages of weather that create climate change, there is a tendency to deny recognition. When evidence supports human activity is changing global climate, many choose to ignore it. In that regard, we continue to live in the dark ages with animals unable to perceive long-term change. We have the ability to adjust our behavior based on the evidence or ignore it.

School cancellations and delays


 

Occasionally, adverse weather conditions or other emergency situations may make it necessary to cancel school, delay the start of school, cancel evening activities or run buses on main/paved roads only. When these situations occur, notice will be communicated to WOOD TV 8, WXMI Fox 17, and WZZM TV 13 through the Grand Rapids Area Information Line (GRAIL) to all subscribing area media.

In the event of a 2-hour delay, students will be picked up by the bus approximately 2 hours later than their routine pick-up time. Morning Early Childhood Special Education (ECSE) and morning preschool classes will be cancelled.

Campus Kids will be open on days that school is closed and / or delayed unless otherwise noted in school closing announcements.

Buses will not transport students to Kent Career and Technical Center for 1st session when a school delay or cancellation is issued. Students will be given a weather-related absence at KCTC when we are officially not transporting them. Students who choose to drive personal vehicles to KCTC on school delays or cancellations assume responsibility for their decision.

When school evening activities are cancelled, this cancellation also includes all clubs, organizations and extra-curricular events held on campus and scheduled for that evening.

For more information, please visit www.csredhawks.org/Parents/Emergency-Notification/index.html or call 616-696-1204.
