Here’s a great description of the breeze and the picking up of the wind.
“One day the breeze became a strong gust and the gust became a gale. The letters clung to the leaves with all their might — but some were blown away, and the others were very frightened. When the storm had passed, they huddled together in fear, deep in the foliage of the lower branches.”
Note the words breeze, gust, gale, and clung. Try one of those on for size in your writing!
