what is a calima in lanzarote

A calima is a hot and oppressive wind that occurs when there is high pressure over the Sahara, which drives a southerly wind towards Lanzarote, bringing Saharan temperatures and sand with it. The phenomenon can be seen on satellite photos, appearing as a cloud-like swirl throughout the islands, which traps the heat close to ground level. During a calima, the air turns a white or even a yellow color, and visibility is reduced. The temperature can rise to very high levels, and people tend to stay inside and avoid any exercise. The calima can last from half a day up to three days, and everything on the island is covered in a film of sand afterward. Occasionally, a calima can be severe and lead to the closure of the airport, as aircraft are unable to conduct a visual approach. The phenomenon is quite a normal part of life in the Canary Islands and Lanzarote, and it is worth noting the forecasts when a calima is announced, especially for people who suffer from asthma or respiratory illnesses due to the high level of dusty sand in the atmosphere.
