The temperature increase experienced on the ocean surface causes increases in wave forces on a global scale.
The rise in sea level together with global warming puts the coastal regions in great danger. Another major sorun facing coastal areas is the increasingly strong waves.
The energy of ocean waves is increasing globally, according to a study published Jan.14 in the journal Nature Communications.
Many long-term predictions and timelines bear the traces of global warming. The rise in sea level, rising global temperatures, and the decrease in sea ice are the most well-known topics. Researchers finally found an increase in sea winds and wave strength.
The new study focused on global warming and wave force, which were previously unclear. Energy in ocean waves comes from winds. Wind patterns begin to change as the surface temperature of the ocean increases, resulting in stronger waves.
Borja G. Reguero, the author of the study, revealed that the wind force özgü increased by 0.4 percent since 1948 and this increase is due to the temperature increase at the sea surface. According to the other author of the study, Inigo J. Losada, climate change affects the oceans in different ways. These changes include the atmospheric cycle and water temperature rise.
Understanding the impact of global warming on waves is particularly important for coastal cities and islands. Changes in waves and changes in wind flow bring some infrastructure, technical and construction problems. Waves and currents are of great importance both in the construction of structures such as ports and in the construction of breakwater-like structures that protect the shores.
The study also revealed that this energy increase manifests itself especially during periods of intense storms and is effective in both hemispheres. Fernando J. Mendez, another author of the study, says that this effect is much more pronounced, especially on the coasts where people and the ocean come together.
