![]() It rises due to convection, resulting in a valley wind. ![]() During the day, the sun quickly warms the air in the mountains, while the valley stays comparatively chilly. Mountain and valley winds originate in the same way as sea and land breezes do. What, therefore, is the source of a valley breeze? On clear days, a wind sweeps up valleys or mountainslopes, which is known as a valley breeze.Īs a result, what exactly are mountain winds? Mountain wind is defined as a diurnal breeze that is influenced by the unevenness of land surfaces and blows down the hill at night. Similarly, what is the definition of Valley Breeze? This is due to the fact that higher elevation mountain slopes cool faster than lowlands. As the sun sets and darkness falls, the air flow reverses. A valley breeze is a mild upslope breeze. Here are 6 characteristics of a valley breeze.ĭuring the day, the warmer, less dense air near the ground rises, pushing additional air through the valley floor. Such breezes can reach speeds of up to 100 miles per hour and are known for their warm gusts that make you feel instantly cooler when they hit your face.Ī valley breeze is a type of wind that typically blows down the center of a valley. In this sense, it’s often used to refer to winds from the ocean or large bodies of water. In general, a valley breeze is typically defined as air that flows down through valleys and across the plains. Along with temperature and moisture levels, breezes can also carry odors into an area The wind coming down from higher elevations breaks up what would otherwise be oppressive heat and humidity, making for a pleasant respite. It does not store any personal data.The warm breeze that blows in from the valley is a great relief to the inhabitants of hot climates.

However, at night the temperature difference between mountain slopes and free atmosphere at the same elevation is reversed. Occasional afternoon thundershowers on warm and humid days may also be produced by this kind of upslope winds in the mountainous regions. The valley breeze is sometimes accompanied by the formation of cumulus cloud near mountain peaks or over escarpments and slopes. ![]() Anabatic wind is another name given to valley breeze. This upslope breeze is called the valley breeze. This results in warm air moving up along the slope. During daytime the slopes of mountains heat up rapidly because of intense insolation, but the free atmosphere at the same elevation over the lowlands is not heated to the same extent. These winds are chiefly caused by temperature differences between two points at the same elevation, but with a different distance from the earth’s surface. In other words, these diurnal wind systems develop frequently over areas with large differences in relief. This day-time up valley winds and nightly down-valley winds are commonly found in the mountainous regions.
