| Summary: | Tropical cyclones that have wind intensity equal or higher than 119 km/h, when formed in the western sector of
the tropical Pacific Ocean, are called typhoons. These systems are responsible for great devastation over continental
areas. Two cases that reached the Philippines and attracted the international attention were the typhoons Haiyan and
Haima. Haiyan was the strongest typhoon recorded since 1979 in the western Pacific and remained active from 3 to 11
November 2013. Haima was the second typhoon that reached winds with an intensity exceeding 220 km/h since 1979.
The purpose of the present study is to describe the evolution of the lifecycle of Haiyan and Haima typhoons (lagrangian
analysis), to show similarities and differences between them, and to evaluate the impact of these systems on atmospheric
variables close to the Philippines (eulerian analysis). The atmospheric variables used in the study were obtained from the
Global Forecast System Analysis and the Tropical Rainfall Measuring Mission. The cyclogenesis region of the Haiyan
and Haima typhoons showed positive sea surface temperature anomalies of 0.7 °C and 1.1 ° C, respectively. Along the
trajectory, the typhoons produced a cold trail on the ocean. Near the Philippines, the Haiyan caused winds with an intensity of 232 km/h and the Haima of 226 km/h. Regarding the lifecycle of these systems, the maturation phase shows
more intense cyclonic relative vorticity and the highest zonal departure of air temperature in the core of the typhoons in
relation to the neighborhood |
