How troughs and ridges shape weather forecasting

AUSTIN (KXAN) -- Meteorologists study the upper levels of the atmosphere to better understand troughs and ridges, which helps them predict both day-to-day weather conditions and long-range patterns. These atmospheric features are key to understanding larger weather systems.

Troughs are areas of low pressure, often linked to unsettled weather. As air converges and rises within a trough, it cools and condenses, leading to cloud formation, precipitation, and potential storms. Troughs can also contribute to the development of low-pressure systems, which can deliver severe weather to our region.

Ridges, on the other hand, are areas of high pressure where air tends to sink, resulting in clearer skies and more stable weather. Ridges are typically associated with dry conditions and warmer temperatures, as they prevent clouds from forming and prevent storm activity.

By tracking the movement and intensity of both troughs and ridges, meteorologists can make more accurate forecasts, predicting everything from significant temperature shifts to severe weather.
