Labrador Current plays a big role in climate formation

Water currents play a large role in the formation of the land climate. For example, Europe owes its temperate climate to the Labrador Current, which will be discussed.

Types of currents

Before we talk about this water stream, you should understand what they are in general. All sea currents are divided into two large groups: warm and cold currents. The first are directed from low to high latitudes (for example, the Gulf Stream). The second is the opposite. Labrador current is a vivid example of this type of flow.

cold currents

In addition, the currents are also underwater and surface; irregular, periodic and permanent. For their classification take different signs: the nature of the movement, stability and others.

Current location

The Labrador Current, whose name derives from the name of the Labrador Peninsula, originates in the Baffin Bay of the Atlantic Ocean.Further, passing through the Strait of Davis, descends to the island of Newfoundland in the east. At this point the flow of water is divided into two branches, which are reunited in the Cabot strait. Further, the current, washing the coast of North America, carries the Atlantic waters all the way to Florida, where it meets with the fast and warm Gulf Stream, deviating to Europe, and goes to the depths. Simply put, it flows between Greenland and the shores of Canada.

direction of the Labrador current

The current is formed by two water streams: the warm West Greenland and the course of the Baffin Sea. The direction of the Labrador Current is directed to the south, with one of the water flows passing through the continental shoal, the second moving along the slope.

Hydrological properties

Now it is necessary to understand: Labrador current is warm or cold. It belongs to the group of cold water streams. A significant role in the formation of the temperature regime is played by the cold and slightly salty current of the Baffin Sea, whose physical characteristics predominate throughout the course.

In winter, surface water temperatures range from -1 degrees in the north to five degrees in the south.In summer, the temperature rises no higher than ten degrees Celsius. And at the meeting point of the described flow with the Florida Gulf Stream there is a difference in temperature. This is especially noticeable in the spring months, when this difference reaches fifteen degrees. Fogs are often observed in this region due to the rather rapid cooling of surface golfstream waters during the movement of air from a warm region to a region of cold waters. This also contributes to the formation of cyclones - air masses with reduced pressure in the center.

Labrador current is warm or cold

Unlike relatively constant temperatures, the flow rate can vary greatly in different places. For example, the speed in Baffin Bay reaches ten kilometers per day. For comparison, along the Labrador Peninsula, it sometimes increases to nearly sixty kilometers. In the Gulf of St. Lawrence speed decreases (but sometimes it can grow) and varies from twenty to seventy seven kilometers a day. Further, the speed is maintained within 20-35 kilometers. Closer to the Florida Peninsula, it is reduced to ten miles per day.On average, the flow rate is 25-50 centimeters per second.

Due to the fact that the waters of the Labrador stream originate from the Arctic Ocean, they are slightly saline (up to 32 ppm).

Environmental impact

The course plays an important role in shaping the climate of America as well as Europe. The cold water flow reduces the summer temperature and affects the amount of precipitation in the north-east of the mainland. Due to the rather low temperatures of the current on the Labrador Peninsula, it is cool in spring and summer (the temperature in July is not more than 11 degrees).

If in the west of the mainland under the influence of the Alaskan stream, it rains in January, at the same time in the east there is a 30-degree frost.

The Labrador Current transports a large number of icebergs to the south. It thus creates a great threat to navigation in the Atlantic all the way to Newfoundland. Thus, the famous Titanic in history sank in the Atlantic Ocean after colliding with an iceberg that brought the Labrador Stream.

Thus, warm and cold currents play an important role in the formation of climatic zones, the formation of cyclones and anticyclones, and also affect the animal and plant life of the land, seas and oceans.
