Discussion: An important technique to estimate the strength of tropical cyclones is known as the Dvorak technique. The Dvorak technique, developed by Vernon Dvorak is a satellite-derived system to estimate storm strength solely based on visible and infrared satellite imagery. The system uses cloud patterns visualized through satellite imagery and can then be used to indirectly measure wind speed and central pressure. Today the Dvorak method is used mainly as verification to measure wind and pressure. This important technique is even used by the National Hurricane Center. What makes this system useful and accurate is because storms with approximately similar intensities were found to contain similar cloud pattern identified on satellite imagery.
