This is due to the North Atlantic Drift, a warm water ocean current, an extension of the Gulf Stream. This current keeps the ports along the coasts warm enough to stay open year-round.

Importance of the North Atlantic Drift
The ports of the Baltic Sea remain open for trade during winter primarily due to the influence of the North Atlantic Drift, a warm ocean current that drastically affects the region's climate.
How the North Atlantic Drift Works
- The North Atlantic Drift originates from the Gulf Stream, which carries warm water from the tropics towards Europe.
- As this current flows northeast, it moderates the climate of the regions it passes, including parts of the Baltic Sea.
Impact on Winter Temperatures
- The warm waters of the North Atlantic Drift raise the air temperatures above the Baltic Sea.
- This phenomenon prevents the sea from freezing over, allowing for continued maritime trade and navigation.
Comparison with Other Factors
- Option a) "It lies in the tropical belt" is incorrect as the Baltic Sea is situated at higher latitudes, not in the tropical zone.
- Option c) "Local winds keep it warm" is not the main factor; while winds can influence weather, the primary reason is the warm current.
- Option d) "Western disturbances cause an abrupt rise in temperature" is more relevant to the Indian subcontinent and does not significantly affect the Baltic climate.
Conclusion
The North Atlantic Drift plays a crucial role in maintaining navigable conditions in the Baltic Sea during winter. Its warm waters prevent ice formation, enabling ports to stay operational and facilitating trade throughout the colder months. This unique climatic influence highlights the significance of ocean currents in shaping regional weather patterns.
