In some regions, föhn winds are associated with causing "circulatory problems", headaches, or similar ailments. Researchers have found, however, the foehn wind's warm temperature to be beneficial to humans in most situations, and have theorised that the reported negative effects may be a result of secondary factors, such as changes in the electrical field or in the ion state of the atmosphere, the wind's relatively low humidity, or the generally unpleasant sensation of being in an
Type 079-class landing ship 1972 to January 1977 revealed the performance was somewhat satisfactory, but the speed was slow and the ability to operate in bad weather condition is poor. Work immediately begun on redesign named as Type 079II-class, while the first unit subsequently became named as Type 079I. A total of 31 were built, including the conversion of the sole Type 079I to Type 079II standard. 26 were completed by Guangzhou Shipyard International, and 4 were completed by Xiamen Shipyard. Like its predecessor Type 079I, the Type 079II was also designed by 708th Research Institute. The main difference between 079I and 079II is
