Nautical Radio Service and Communications Service
The Croatian coasts coverage by radio communications is satisfactory. The radio service for the protection of human lives and safety of navigation is provided by Plovput from Split through radio stations Split and Dubrovnik, which cover the southern Adriatic, and Rijeka, which covers the northern part of the Adriatic sea.
According to the standards of the GMDSS system (Global Maritime Distress and Safety System), the channel for automated receipt of digitalized distress calls is the channel 70, after which the communication is transferred to the operating channel of the coastal station, i.e. a harbor master's office (16 or 10). GMDSS system has been in use since 1st February 1999, and on the present VHF channel for distress calls, the channel 16, constant listening will be possible still for some more time.
For a direct call to a harbor master's office, the channel 10 is used.
In Croatia, there are three commercial systems of wireless telephony: mobile phone 099, Cronet 098 and VipNet 091.
Winds
Bora (Bura) is the strongest wind along the Adriatic coast, blowing with enormous strength in some locations, mainly in the northern parts of the Adriatic. It is a dry and cold downward wind, blowing in bursts from the north-northeast to the east-northeast direction. The direction in which the wind blows is mostly influenced by the configuration of the shore. The strength of bora is explained by the existence of warm air over the surface of the sea, and a cold layer of air above mountain ranges in the littoral, which cause a strong streaming due to equating of the pressure. Cold air tends to fill the void, which occurs due to the rising of the warm (lighter) air from the sea surface. Bora blows mostly in the winter. In the summer, it usually lasts for a day or several hours, while, in the winter, it can blow as long as 14 days.
Sirocco ( jugo, šilok) is a warm and moist wind which blows from the direction east-southeast to south-southwest. Its consequences are high waves and rain. Sirocco is a characteristic wind for the southern Adriatic, where it blows longer and stronger than in the northern part. In the summer, it usually blows as long as 3 days, and in the winter even as long as 3 weeks. The signs of the oncoming sirocco are the calm at the sea, weak changeable winds, dimness of the horizon, the increase of the temperature and moisture, and the gradual decrease of the pressure. Waves from the direction of the southeast become bigger.
The landward breeze ( maestral) is a daily, thermic wind blowing from the direction of the northwest, and it occurs as the consequence of the difference in the speed of warming up of the land and the sea. It is present from the spring to the autumn, and, during the day, it often changes the direction of blowing. The landward breeze is more present in the southern Adriatic than in the northern Adriatic, and it starts to blow earlier there.
The stiff breeze (burin) is a wind blowing contrary to the landward breeze. It blows during the night from the direction of the north, north-east in the northern Adriatic, and in the southern Adriatic, from the east or south-east. It is the strongest before the dawn, and after that it stops soon.
