Microsoft SQL Server Analysis Services provides for the use of functions in Multidimensional Expressions (MDX) syntax. Functions can be used in any valid MDX statement, and are frequently used in queries, custom rollup definitions, and other calculations. This section provides information about the MDX functions included with Analysis Services.
A hurricane needs humidity to develop. Humidity is the amount of  water in the air. A hurricane starts off as a series of  thunderstorms which intensify as it moves over the â¦ warm humid sea.  The humidity continues to grow over the sea. Any sort of decrease  or increase in humidity can change the strength of a hurricane.
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm. And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes. Satellite data shows the heat and energy transfer in action. Notice how this hurricane leaves a trail of cooler water behind.
