Undular Bores (Atmospheric Gravity Waves)

I captured spectacular gravity waves on radar this morning. Also known as undular bores, these are waves in Earth’s atmosphere that often show up quite well on satellite and radar imagery.

Heat Index Calculator & Charts

The heat index is an estimate of how hot the air “feels” to the human body and provides a relative indication of potential health risks. Among others, the two primary factors in the heat index equations are temperature and water vapor (i.e., moisture/humidity). Humidity affects the efficacy of perspiration to evaporatively cool the skin. When […]
