Abstract
<p> Weather chart-based atmospheric pressure data samples over a period of 47 years were gathered to estimate the radius to the typhoon-generated maximum wind speed, so-called typhoon radius R. Any of the 6 kinds of data samples shows that the radius R increases very slowly at first and then increases more rapidly with increasing central pressure of the typhoon Pc, although the relation has been associated with large data scatter. Next, data samples of wind speeds in typhoons over a number of years were analyzed by using Myers's pressure pattern-based gradient wind speed model corrected for the speed of advancement of the typhoon. Using this model, the estimated typhoon radii, similarly to the pressure-based results, show a consistently slow increase followed by a rapidly increasing trend with the central pressure, but the rate becomes increasingly smaller than that of the former case.</p>
