Strong and Noisy

It is amazing that we can feel or hear some weather occurrences but not actually see them. We can hear and feel that it is windy outside but it is invisible. We can “feel” heat or cold but not see it. The wind is one of those natural occurrences that we can perceive in another way besides visualizing it, although we can see the effects of it as it sways trees, wave’s flags and creates mini funnel clouds of dust.

The high pressure system over south central Texas has affected our wind patterns lately and makes me think of how I was taught as a child about the month of March, even though it is June – comes in like a lion (with winds, rain, extreme weather), and goes out like a lamb (calm, comfortable temperatures, predictable weather). The strength and power of this invisible force called wind is startling sometimes. Jumping on the trampoline, a 50 pound child can be swayed by the intensity. An adult walking along a ridge can be zigzagged. Tree limbs bend and twist. Oak branches and leaves are knocked off of the tree and pound on my roof, as just happened moments ago. The gusts are what just occurred there, an inconstant blast of wind characterized by the rapid change in the force and/or direction of the wind.

Wind is a mysterious force that feels good when it is warm, awesome when it is the perfect temperature, and awful when it is too cold. It is simply air in motion, caused by the uneven heating of the earth, absorbing the heat of the sun at different rates. During daylight hours, the air above land heats up more quickly than the air over water. The warmer air particles over land expand and rise, and the heavier, cooler air rushes in to take its place, creating winds. Cool.

The other way we know about wind is by its sound. The sound of the wind must have something to do with the air particles being so compacted and forcefully pushed around that we hear it. It is also the noise of the various items that are tossed and pressed together with the wind – plant and tree leaves, grasses, insects and other dirt and debris – clattering and banging around to howl or moan.

The wind intrigues and stimulates me. I take comfort in the fact that the wind will blow as long as the sun still shines.
