A continental climate, large annual temperature range. Water molecules are slow to respond to heat gain or loss. Over continents, a greater percentage of radiational surplus dissipation occurs by sensible heat flux. Water is transparent , light penetrates to about 200m depth. Solar energy received can be stored in a large volume.
Land surface is opaque.
Heat surplus concentrated immediately at soil surface. Water is fluid, so heat can be redistributed by convection currents . This permits greater storage of heat surplus. Land surface is solid, so molecules can only vibrate more when they absorb radiation. C. Ocean currents .
