If global oceans of methane exist on Titan, the atmosphere above them must be within 2 percent of saturation. The two Voyager radio occultation soundings, made at low latitudes, probably occurred over land, since they imply a relative humidity less, similar 70 percent near the surface. Oceans might exist at other low-latitude locations if the zonal wind velocities in the lowest 3 kilometers are </= 4 centimeters per second.
如果泰坦上存在全球性的甲烷海洋，那么它们上方的大气层必须接近饱和的 2%。两次航海者号无线电掩星探测都在低纬度进行，很可能是在陆地上进行的，因为它们暗示了相对湿度较低，在地表附近接近 70%。如果在最低 3 公里处的纬向风速<=4 厘米/秒，那么海洋可能存在于其他低纬度地区。
