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.
Humidity partially controls the moisture that's lost from a plant. Plants growing in dry rooms lose moisture, which can harm many plants. Not all houseplants need the same levels of humidity. While desert houseplants such as cacti need about 30 percent humidity, others native to tropical rain forests require much higher humidity levels, as high as 90 percent. Plants needing higher humidity do best when grown in closed containers such as terrariums.
