The hydrozoan Portuguese man-of-war (Physalia physalis) is distributed throughout the Havana littoral zone, which is one of the circulation points of the currents that form the North Atlantic Subtropical Gyre run. For the first time, a study was conducted monthly from May 2018 through May 2019 to better understand the temporal and spatial variation of P. physalis in this region. This study covered five beaches in Havana (Cojímar, Bacuranao, Tarará, Mégano and Santa María). Transects of 50 m were located parallel to the shoreline and the colonies that arrived at the intertidal zone were counted. The colonies of P. physalis were mostly observed in May 2018 (80), November 2018 (110), December 2018 (132), January 2019 (152) and March 2019 (126), which coincided with the dry season in Cuba. This season was related to the presence of cold fronts and a negative average magnitude of the Arctic Oscillation Index (-0.05). The beaches with a relatively linear shape had a higher number of arrivals (549 colonies) than the beaches with a horseshoe shape (109 colonies). In addition, the highest number of colonies was associated with wind velocity above 33 km.h⁻¹ (especially northerly wind), wave height above 1.5 m, and temperatures below 30 °C.

水生动物的葡萄牙战役者（Physalia physalis）分布在哈瓦那沿海地区，这是形成北大西洋亚热带环流的水流的流通点之一。从2018年5月至2019年5月，每月首次进行一项研究，以更好地了解该地区酸浆的时空变化。这项研究涵盖了哈瓦那的五个海滩（科伊马尔，巴库拉瑙，塔拉拉，梅加诺和圣玛丽亚）。50 m的样线平行于海岸线，并计算了到达潮间带的菌落。酸浆假单胞菌的菌落主要在2018年5月（80），2018年11月（110），2018年12月（132），2019年1月（152）和2019年3月（126）观察到，这与古巴的旱季相吻合。这个季节与冷锋的存在和北极涛动指数的负平均幅度有关（-0.05）。具有相对线性形状的海滩比具有马蹄形的海滩（109个殖民地）具有更高的到达数量（549个殖民地）。此外，菌落数量最多的原因是风速高于33 km.h ^-1（特别是北风），波高超过1.5 m和温度低于30°C。
