At times a cold front overtakes a sometimes slower moving warm front. The warm front gets pushed aloft the cold front when this occurs. An occluded front is the line formed in-between the 2 fronts as they continue to move together. Light rainfall and Stratus clouds typically go with the occluded fronts. A stagnant area is created when 2 air masses that are dissimilar but not powerful enough to bump and replace the other meet. Precipitation for a while period accompanied by cloudy weather leads to due to this stagnant situation. This stagnant front may as a warm or cold front start to move or after some days may dissipate. In summer the possibilities of occurrence of such stagnant fronts are higher. More than seventy percent of the Earth's surface is covered by the seas. Land surface does not cool down or heat up as quickly as the water surface and thus heat is efficiently stored in seawater. Due to this characteristic cold or warm water is carried to different parts of the world by sea currents. The temperature of the currents below has effects on the temperatures on the surface.

Changes in temperatures of the sea change climates.

It has effects on more effectively the climate of the tidal area. In the few weeks round the summer and winter solstices the maximum and minimum sea temperatures legs due to the slow heating and cooling nature of water. The weather is touched by the variation in sea and land temperatures that gets increased due to this lag. As a consequence massive portions of the water surface may experience mists and the weather in the tidal area could be cooler. In the air the water vapor gets condensed to form clouds that ultimately as rain falls down on the Earth surface. The entire process starts all over again as the majority of it is going back to the oceans after a little portion of it is getting soaked up by snow and rain.
