yes it is true that only warm ocean currents that influence climate
The influence of the ocean (notably the Gulf Stream) allows French climate to be somewhat mild during winter and that influence can still be felt in Paris, which is only 200 km East of the English Channel and 450 from the Atlantic Ocean. Otherwise Ocean currents have no effects on the Seine river going through Paris.
The three types of ocean currents are surface currents, deep currents, and tidal currents. Surface currents are driven by winds, deep currents are driven by density and temperature differences, and tidal currents are driven by the gravitational pull of the moon and sun.
Ocean currents follow regular patterns related to the Earth's rotation, prevailing winds, and differences in water density caused by temperature and salinity variations. These factors influence the direction and speed of the currents, creating complex circulation patterns in the oceans.
Ocean currents carry warmer water from the tropics into colder regions. The heat from that warmer water escapes into the atmosphere as it travels, creating warmer, rainier weather than might otherwise be expected. Upwellings along the California coast bring cold water up from the bottom of the ocean. This is why beaches along the continental pacific coast never really have warm water (compared to the Atlantic coast) even in summer. Winds carry this ambient temperature onto land which is why the coast of California remains in a range between about 50-75 degrees all year long. Climates that rely on ocean temperatures in coastal regions are considered "Maritime" climates. The Sierra mountains inland force air up the mountain slope, which results in precipitation and rain shadow on the leeward side of the range. The climate in this area is very hot and dry, resulting in the deserts in the western US. This is considered a "Continental" climate because it is not really affected by the ocean temperature. Continental climates typically have much more drastic temperature changes not only in different seasons, but also diurnally (daily). Winds are the result of air moving from different areas of high and low pressure. The larger the different in pressure, the stronger the winds become. Winds and ocean currents are responsible for distributing warmer temperatures from the equator to the rest of the world.
Only when the oceans flood the land.
I only know one factor, the MOON
Trade winds significantly influence ocean currents by driving surface water movement in tropical regions. These winds blow predominantly from east to west, pushing warm surface water in the same direction and creating currents like the North and South Equatorial Currents. This movement not only redistributes heat across the oceans but also impacts weather patterns and marine ecosystems. Additionally, the interaction of trade winds with the Earth's rotation contributes to the formation of gyres, which are large circular current systems in the ocean.
Due to ocean currents
Climates cannot be classified solely by latitude because other factors, such as altitude, proximity to oceans, prevailing winds, and geographical features, significantly influence local climate conditions. For instance, coastal regions may have milder temperatures than inland areas at the same latitude due to the moderating effect of ocean currents. Additionally, mountainous regions can experience varying climates over short distances due to altitude changes, which latitude alone cannot account for. Thus, a comprehensive understanding of climate requires considering multiple environmental variables.
Latitude is only one factor which determines the climate or even simply the rainfall pattern, temperature pattern etc. The climate is also determined by wind pattern, relief(how high the place is) etc.
Current relays are the relay which sens the current passing in particular circuit and operates when this current exceed its set value.
Ocean currents at the SURFACE -- their primary cause is SOLAR ENERGY. Due to solar energy, much of the wind pattern originates and this wind pattern in turn causes ocean currents on the surface.
