The article presents numerical characteristics of the spatial distribution of type and height of tides in the World Ocean according to the data of three global tidal models: EOT20, FES2014 and TPXO9. To obtain these estimates, a preliminary comparison of methods of determining tidal types was carried out. An algorithm for quickly pre-calculating tide heights for a long period of time for a grid area covering the entire World Ocean was also developed. Moreover, a method for calculating the probability density function of the spatial distribution of tidal characteristics was implemented. The characteristics of the tide were determined both in the entire World Ocean and in individual oceans. In addition, estimates of changes in tide characteristics depending on latitude, distance to the coast and sea depth were obtained. Mean, median and mode values of tidal heights and types were calculated. Our results showed that the main patterns of distribution of tidal characteristics remain unchanged regardless of the chosen global tidal model. It was revealed that the semidiurnal type of tide dominates over the entire area of the World Ocean. The distribution of frequencies of occurrence of various heights in the World Ocean and in its individual parts has been determined for the first time. It has been established that the probability density function of tide heights has a single-mode distribution with positive skewness. The most common are average tidal heights equal to 0.6 m and extreme tidal heights equal to 0.9 m. The dependence of the characteristics of tides on latitude is most clearly manifested. Nevertheless, this dependence is not symmetrical relative to the equator. The spatial distribution of tidal types does not depend on sea depth and distance to the coast, while tide heights decrease with distance from the mainland.
