Some also falls a short distance downwind of the ridge and is sometimes called spillover. In the occluded stage of the life cycle of an extratropical cyclone, when cold air west of the surface low-pressure centre advances more rapidly toward the east than cold air ahead of the warm front, warmer, less-dense air is forced aloft. During the winter season, the polar front is generally located at lower latitudes and is more pronounced than in the summer.

Cumulonimbus clouds routinely form in the tropics where rising parcels of air are warmer than the surrounding ambient atmosphere. In locations where the ground is heated by the sun, such as the Tropics, convectional rainfall is common. (Name of Operation) Since motion upward into the stratosphere is inhibited by very stable thermal layering, the air transported upward by convection diverges toward the poles in the upper troposphere. This rain flows into rivers and streams and these rivers and streams bring the water back to the sea where the cycle begins again.

Based on the temperature, precipitation has many forms. (For a given location on Earths surface, the highest daily temperatures are achieved just after the period of greatest insolation, since time is required to heat the ocean surface waters and the soil.). The tropical rain belt stretches out in a virtually unbroken line across the open ocean.

Sea surface temperatures around northern Australia are cooler than normal and the focus of convection migrates away from Australia eastward towards the central tropical Pacific Ocean. Convectional rainfall appears to be caused by warm air rising from the earths surface and water vapor condensing at a higher height. This circuit of rising and falling air is called a convection cell. Symonston ACT 2609. Types of Rainfall. The preconditions for this kind of rainfall are intense heating of the ground surface by incoming shortwave electromagnetic solar radiation and ample supply of moisture caused by evaporation to the air to result in high relative humidity.
