Abstract

Internal variability of the environment is one of the most studied variables in the meteorology field. The internal variables that affect the Atlantic Basin are the North Atlantic Oscillation (NAO), Artic Oscillation (AO) and the Southern Oscillation Index (SOI). Many studies have been conducted where they show the relation between the number of hurricanes by season and the period of the internal variables of the environment. Though many of these studies are done over the Pacific Ocean, neglecting the Atlantic Ocean. This research focus on finding the relation between the internal variables of the environment with the hurricane trajectory. We inferred that when the indices are in a positive period the hurricane path will be recurved and when the indices are in a negative period the hurricane will have a straight trajectory. Result shows, that the NAO does not have a correlation with the trajectory of the hurricane. The SOI and AO have a high correlation between hurricane trajectory and the indices. For both the SOI and AO there was at least 50 % agreement with the assumption of the relation of the difference in the positive/negatives periods of the internal variable of the environment.
