The phenomena
Some south Vietnamese, especially adolescent women, that were evacuated to Israel. They always wore heavy knitwear for several months afterwards, until they had got acclimatised.
The reason
It was caused by the major temperature and humidity differences between S. Vietnam and Israel.
- Temperatures are ~25%-50%. less in Nasareth. Humidity is ~20%-50% less in Nazareth. Rain fall is ~25%-66% less in Nazareth. The number of rainy days is ~100%-50% less in Nazareth. Sunshine is ~25% more in Nazareth. With the exception of sunshine, it is a missive climatic drop like that between summer and winter, hence the knitwear. Most of them wore cardigans, not jumpers, since that was the global feminine fashion trend at the time.
This did not happen in Manila and Bataan since it was much more like S. Vietnam's climate.
- Temperatures are ~10% less in Manila. Humidity is ~20% less in Manila. Rain fall is 20% more in Manila. The number of rainy days is the same in Manila. Sunshine is 10% less in Manila.
