Turkey’s ruling AK Party on Wednesday ordered protesters to leave Istanbul’s central Gezi Park immediately and said it would consider holding a referendum on redevelopment plans which sparked almost two weeks of violent demonstrations. “Those with bad intentions or who seek to provoke and remain in the park will be facing the police,” Deputy Chairman Huseyin Celik told a news conference.
What kind of cloud is this? A roll cloud. These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. Unlike a similar shelf cloud, a roll cloud, a type of Arcus cloud, is completely detached from their parent cumulonimbus cloud. Pictured above, a roll cloud extends far into the distance in 2009 January above Las Olas Beach in Maldonado, Uruguay.
