Archipelago

Archipelago is the term used to describe a group of islands at sea. During the ice age, the melting of ice liberated rock that emerged in the form of many small islands. Even today countries do not stand still and islands continue to form.

Azores High

The Azores High is a high pressure area which is part of the subtropical high pressure belt. The Azores High is an important control center for the weather in Europe.

Balancing coasts

Balancing coasts are flat and mostly straight. The beach is continually moving due to the constant activity of water and wind.

Beaufort

The Beaufort scale describes the classification of winds by their speed.

• 0 Beaufort (Bft.): completely calm and glass like waters
• 1 Beaufort: minor ripples
• 2 Beaufort: a light breeze associated with small, short waves
• 3 Beaufort: a light breeze
• 4 Beaufort: a light breeze with small waves that grow longer
• 5 Beaufort: moderate winds
• Up from 6 Beaufort: strong winds
• Up from 7 Beaufort: trees sway and it can be difficult to walk against the wind
• As of 8 Beaufort: can be very dangerous. There are stormy winds associated with high peaks
• 9 Beaufort: a storm with high waves
• 10 Beaufort: a severe storm with high waves
• 11 Beaufort: a hurricane-like storm, where severe damage to buildings and cars can occur. Visibility is greatly reduced and the water is blown horizontally
• 12 Beaufort: the highest possible speed and creates a hurricane.

Blue water sailing

Blue water sailing allows for free sailing and life at sea. During blue water sailing one stays out in the open sea for a long time without anchoring. This requires a lot of preparation as the boat must be well equipped for the route, so it can be self-sufficient for weeks or months at a time.

Bodden coast

Bodden coasts are broad, shallow bays at flat coasts. They were created by the flooding and undulating moraine landscape after the ice age.

Bora

The Bora is a dry, cold and gusty wind that makes the east-northeast wind. It rages between Trieste, the Kvarner Bay and Istria, Dalmatia and Montenegrin Adriatic coast. Its gusts can reach up to 200 km / h and are particularly dangerous for sailers in the winter.

Brackish water

A brackish water sea is a body of water (usually in the range of estuaries into the sea), which has a salt content of 0.1% to 1% and can thus be seen as a zone of low salt content.

Burin

The Burin is the opposite of the mistral, its air is running in a closed circuit at night - in opposite directions. It develops after sunset and has usually disappeared by sunrise.

Coastal cliff

Cliffs are formed on coastlines due to waves erroding the rockface.

Continental shelf

The continental shelf is a shallow coastal sea bed that reaches 200 meters below sea level.

Fjord coasts

Fjord coasts are coastlines with elongated bays.

Gulf Stream

The Gulf Stream is a warm ocean current that originates in Florida, USA and crosses the Atlantic Ocean. It has a velocity of 6 km / h. The Gulf Stream is responsible for relatively mild winter in central Europe, as it transports large amounts of energy.

Haff-coasts

Haff-coasts are a special case of balancing coasts.

Humidity

The humidity is the amount of water vapor in the gas mixture in the atmosphere or air, and is an important indicator for health and comfort. Humidity is most comfortable between 40% and 60%. For people, if the surrounding air is too dry, eyes can begin to burn. If it is too moist, mold forms can occur.

Jugo

Jugo is the Croatian word for the smooth, hot desert wind Scirocco. It usually blows in spring, early summer and autumn in a south to south-easterly direction from the Sahara towards the Mediterranean. The greater the temperature difference, the stronger is the Jugo. Because of its formation over the desert it also take great amounts of sand dust with it, when this happens the air gets a yellowish-gray color and can take on the character of a sand storm. The visibility can fall below one kilometer.

Kapeffekte

The Kapeffekt represents a specific type of change in the direction and strength of wind. It is triggered when the wind blows around mountainous areas or headlands. When the wind blows across the cape, it produces  a zone of turbulence on the lee side. In the direct vicinity of the cape it causes a substantial increase of wind and a considerable change in wind direction.

Levante

The Levante is a warm wind (3 to 5 Bft.), which often follows the Mistral and usually occurs in the summer months between June and August.

Lodos

Lodos is the turkish name for the dangerous hot desert wind Scirocco, which usually blows in autumn and winter from the south. At first it blows moderately, but then it increases dramatically. It can be dangerous and create a trap for yachts.

Low pressure area

A low pressure area is an area with lower air pressure than the large-scale environment.

Maestral

Is the Croatian name for the often strong Mistral wind, which pushes the boundaries by a cold front from the northwest in the Mediterranean.

Marina

Marinas are smaller ports that are geared towards the needs of recreational boating.

Meltemi

The Meltemi is a fair-weather wind from the north, it occurs mainly in the summer months in the Aegean Sea and brings cool and pleasant air.

Mistral

The Mistral is created by a cold front from the northwest in the Mediterranean. It is an advancing, often strong, fall wind. It is noticeable in the lower Rhone Valley and beyond.

Nautical mile

The nautical mile (nm) is a unit of length used by sea and air navigators wordwide. 1 nautical mile is equal to 1852 meters (m). In terms of speed, the nautical mile per hour is also known as nodes.

Navigation

Navigation is an art. The goal is to move a boat safely to the desired destination. Good navigation is achieved by detecting the current position (localization) and determining the best route to the destination.

Northeast trade winds

Moderately strong and very steady wind that occurs in the northern hemisphere.

Scirocco

The Scirocco is a smooth, hot desert wind from the south/south-easte. It usually blows in spring, early summer and autumn from the Sahara towards the Mediterranean. The larger the temperature difference, the stronger is the Scirocco. Because of its formation over the desert, it carries large quantities of sand and dust with it. The air becomes a yellowish-gray color and can take the nature of a sand storm. Visibility can drop below one kilometer.

Shoal

A shoal is a shallow area of water that causes a threat to shipping. Most of them are marked on nautical charts, so that the risk may already be detected.

Southeast trade winds

The moderately strong and very steady wind occurs in the southern hemisphere.

Thermals

Thermals can be regarded as a kind of "air conditioning" of the earth. Thermals develop due to radiation warming the earth's surface and the air on the ground. During the day, it brings the air heated by the sun to high altitudes and guides cooler air from several hundred meters above the ground.

Tides

The fluctuating water level of the ocean

Trade winds

Moderately strong and very constant winds that occur in tropical sea areas up to about 23.5 ° latitude around the globe.
There are two main trade winds with different wind directions: the northeast trade winds and southeast trade winds.
