My brothers are awake, testing the weather.
Does it simply mean
they're testing the weather condition?
Or it has another meaning?
Could you please explain it to me?
The fuller text is here:
The hill is paved with wild wheat. If the conifers and sagebrush are soloists, the wheat field is a corps de ballet, each stem following all the rest in bursts of movement, a million ballerinas bending, one after the other, as great gales dent their golden heads. The shape of that dent lasts only a moment, and is as close as anyone gets to seeing wind. Turning toward our house on the hillside, I see movements of a different kind, tall shadows stiffly pushing through the currents. My brothers are awake, testing the weather. I imagine my mother at the stove, hovering over bran pancakes. I picture my father hunched by the back door, lacing his steel-toed boots and threading his callused hands into welding gloves.
