Geography and Climate
Yên Bái covers an area of 6,899.5 km2 (2,663.9 sq mi), and the Red River passes through the province. Yên Bái is a mountain province, characterised by rugged mountainous scenery and green rice paddy fields in the valleys. The Hoàng Liên Sơn mountain range runs through the province. The Red (or Thao) River and Chay River flow the province. Their origin is in the Yunnan, China. The valley created by these two river systems in the Yen bai Province is fertile, though an uneven territory; Muong Lo plain is the rice bowl of the province.
The topography is steep, rising from east to west and from south to north. The average elevation is about 600 metres (2,000 ft) above sea level and can be divided into two regions: low-lying regions on the left bank of the Red River basin and the high right bank of the Red River and in the plateau between the Red River and Da River there are many mountains. Besides the two main rivers, the Red and the Da, the province has about 200 canals, small streams and large lakes and swamps. Thac Ba Lake is situated in the province, an artificial lake which has an area of 23,400 hectares (90 sq mi) and 1,331 islands and hills. It has a capacity of 3 to 3.9 billion cubic meters of water and its original intention was to run the Thac Ba hydroelectric plant, one of the first large hydropower projects in Vietnam. The water in the lake is blue and clear, and reflects the surrounding green forests. The thousands of hills and islands have many caves, including Hum, Cau Cuoi and Bach Xa. A Thac Ba Temple is located in the lake area. Thac Ba Lake has changed the climatic pattern in the western districts of the province, to a moderate condition from its hot and dry status.
The main ecozones of the province are rainforest, subtropical and temperate mountainous zones. It experiences a tropical monsoon season. The 20,293 hectares (78.35 sq mi) conservation area Mu Cang Chai Species / Habitat Conservation Area (MCC SHCA) was established in 2004 to protect the endangered mountain wildlife in Cang Chai district on the border of Lào Cai Province.
The mean temperature in the province at elevations above 1500m is about 20 °C (68 °F) and drops to 0 °C (32 °F) with frost and snow in some parts. December–January are winter months when the climate is dry. Frequent drizzle is experienced during late winter months; this type of rain has earned Yen Bai the epithet "drizzle centre of the country”. April to December are summer months and the rainy period. The mean temperature is stable for the district as a whole and is in the range of 18 °C (64 °F) to 28 °C (82 °F).

Famous quotes containing the words geography and, geography and/or climate:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“Certainly parents play a crucial role in the lives of individuals who are intellectually gifted or creatively talented. But this role is not one of active instruction, of teaching children skills,... rather, it is support and encouragement parents give children and the intellectual climate that they create in the home which seem to be the critical factors.”
—David Elkind (20th century)
