Question

2) Imagine a hail stone of mass.001g falling through super cooled droplets of water. The hailstone starts with a temperature of -10 C. As it passes through the water droplets, they freeze in place on the hail stone, releasing heat and warming the ice. What is the mass of rime that needs to be added to the hail stone to raise its temperature to the melting point? What percentage of the hail stone's mass is this? a) pockets within the ice. With this in mind, describe the relative rates of riming for the hail stone pictured below. (Hint: while freezing ice to the surface adds heat, the hail stone is also conducting heat back out into the air. The balance of these two processes controls the hail surface temperature)

Explanation / Answer

Sea surface temperature (SST) is the watertemperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface.
