drought
For the period 1971 to 2000, the average annual rainfall in the Leicester area was approximately 700 mm
A meteorological map (weather map) is often used to show the current rate of rainfall, and other weather features. Or the map may be printed to show the rate of rainfall for a certain month, year, or for a longer period of time.
prolonged rainfall means literally a large amount of rainfall over a long period of time in geographical terms.
The more rain, the higher the watertable is to the ground surface. Excess water over a short period will cause flooding, and during dry periods the watertable will become lower.
drought
For the period 1971 to 2000, the average annual rainfall in the Leicester area was approximately 700 mm
If, for example, the rainfall is recorded once every week for a whole year, and the recorded results added together, the average would be the total divided by the number of weeks in a year. This will give the average amount of rain that fell during the whole of the year.

A drought is an extended period without normal rainfall.
a long period of abnormally low rainfall is called a "drought."
I understand that The World Meteorological Organization (WMO) specifies that average meteriogical data be calculated over a 30 year period, the most recent period of which ended in 1990. I thought that the UK also released this information annually but I cannot find it - sorry. However, if you check with the Met office on their website - this is free btw - http://www.metoffice.gov.UK/climate/UK/averages/index.HTML - you can search for average sunshine, air frost, rainfall ect and select this information by month and by either country, county, region, town or individual weather station! So the average annual rainfall in England during the period 1961-1990, according to the Met Office's records was 828mm (33 inches, or thereabouts!) Hope this helps! Roo Ellis www.TheHuntingAgency.com
Average speed during a period of time =(distance traveled during the time) divided by (length of the time period)
The period value determines how many observations to average in a moving average model. Moving average is not a real piece of data but a comparison for forecast and valuation.
A drought is an extended period of significantly below average precipitation in a region. NO, drought is a shortage of rainfall or dry weather!!!!!!!
It is called an EPHEMERAL STREAM which is a stream that flows only briefly during and following a period of rainfall or during snow melt in the immediate locality.
