Amounts shows the quantity of the element requested. For example, choosing the amounts column under Rainfall Maps will give a rainfall map of how much rainfall (in millimetres) has fallen for the time period and area chosen.
Amounts of precipitation also vary from year to year. In 1988, an intense drought gripped the Midwestern United States, disrupting agriculture because there was not enough rain to sustain crops.
In Australia, it is described as a storm which carries large amounts of dust into the atmosphere.EarlyUntil two hours after sunrise.El NiñoA major warming of the equatorial waters in the eastern Pacific Ocean.
Flash Flood TableIn hydrologic terms, a table of pre-computed forecast crest stage values for small streams for a variety of antecedent moisture conditions and rain amounts.
In forecasts, snowfall amounts are expressed as a range of values, e.g., "8 to 12 inches." However, in heavy snow situations where there is considerable uncertainty concerning the range of values, more appropriate phrases are used, such as "...
If the forecaster feels that it is warranted, he or she can issued it for amounts less than the minimum criteria. For example, it may be issued for the first snow of the season or when snow has not fallen in long while.
airborne fraction The portion of CO2 released from all energy consumption and land use activities that remains in the atmosphere as opposed to the amounts absorbed by plants and oceans.
It can cause extensive cloudiness and increased amounts of precipitation in higher terrain.
In my experience, dust rain is most obvious with small amounts of rain, certainly less than 1-2 mm, for otherwise much of the evidence is either washed away or so dilute as to be unrecognisable. Perhaps this is the fate of many falls of dust.
The 27th tropical depression in the record-breaking 2005 Atlantic hurricane season develops in the southeastern Caribbean which could bring isolated amounts of between 10 and 12 inches of rain over the Lesser Antilles. (U.S. NHC) ...
aerosol size distribution"The amounts of different size particles of solids or liquids that are suspended in air as an aerosol.
But when the colliding air masses have very different temperatures and amounts of water in them, turbulent weather can erupt. A cold front occurs when a cold air mass moves into an area occupied by a warmer air mass.
Ombrometer A rain gauge capable of measuring very small amounts of precipitation. Also called micropluviometer, trace recorder. Ombroscope An instrument which indicates the presence of precipitation.
In actual rainstorms, particularly thunderstorms, amounts of rain very often exceed the total precipitable water vapor of the overlying atmosphere.
Rather, it is computed using forecasted ozone levels, a computer model that relates ozone levels to UV incidence on the ground, forecasted cloud amounts, and the elevation of the forecast cities.
Many things can reflect small amounts of radar energy including clouds, smoke, and fog. Even atmospheric effects like inversion layers and the variation in air density introduced by temperature variation can produce echoes.
Assess rainfall intensities and amounts, and
Aid in forecast procedures for flash flood watches and warnings, various statements, and river forecasts.
In cases of mixed precipitation or blowing, these snowfall amounts may be less.
''We are not mentioning amounts at this time,'' he said, adding only that it should not be a heavy snowfall. Yesterday's accumulation surprised many people, but they took it in stride because there was no morning rush-hour to contend with.
As this is usually measured in a fixed rain gauge, small amounts of dew, frost, rime, etc., may be included in the total.
Answer: Lake effect snow is a unique weather phenomenon that can produce tremendous amounts of snow in the winter.
Now, it happens that the pressure aloft over different temperatures changes by different amounts, so that the upper isobars are rotated relative to the lower isobars, and this rotation changes the direction of the geostrophic wind.
Rain Gauge - An instrument used to measure rainfall amounts.
Rainbow - Optical phenomena when light is refracted and reflected by moisture in the air into concentric arcs of color.
In the past 200 years (since the Industrial Revolution) the increased burning of fossil fuels has released vast amounts of carbon dioxide into the atmosphere.
Freezing Rain - Rain that falls in liquid form and then freezes upon impact with the ground or an item with a temperature of 32 degrees Fahrenheit or less, possibly producing a thin coating of ice. Even in small amounts, ...
DEWPOINT POOLING (DWPT PLG) - An area, usually along a surface front or trough, where there is a "pool" of higher dewpoints (or higher amounts of surface moisture).
A line connecting points of equal precipitation amounts.
Isopleth
General term for a line connecting points of equal value of some quantity. Isobars, isotherms, etc. all are examples of isopleths.
ISOHYET The line drawn through geographic points recording equal amounts of rainfall during a given time or for a given of storm.
ISOPLETH A line connecting equal points of value. Also called an isoline.
blizzard: severe weather in which there is low temperatures, strong winds and heavy amounts of snow falling or blowing.
(return to top)C
climate: average meteorological conditions in a certain area over a certain period.
In hydrologic terms, a table of pre-computed forecast crest stage values for small streams for a variety of antecedent moisture conditions and rain amounts. Soil moisture conditions are often represented by flash flood guidance values.
TRACE -Precipitation amounts less than 0.01".
TRADE WINDS - Persistent tropical winds that blow from the subtropical high pressure centers towards the equatorial low.
An active weather front with large amounts of precipitation
Anemometer
An instrument that measures wind speed ...
Isohyet- A line of equal precipitation amounts.
Isopleth- General term for a line of equal value of some quantity. Isobars, isotherms, etc. all are examples of isopleths.
Isotach - A line of equal wind speed.
The wind may blow with great force and carry large amounts of dust. It most frequently occurs in the winter months.
Freezing Rain Advisory- Issued when freezing rain or freezing drizzle is forecast but a significant accumulation is not expected. However, even small amounts of freezing rain or freezing drizzle may cause significant travel problems.
Flash floods are increasingly observed in urban areas where the surface is unable to absorb large amounts of water in a short period.
Example: Although the average September to December rainfall in Entebbe from 1902 to 1992 was 438mm, the actual amounts each year were somewhere in between 200mm and 1000mm, which is a large range of values.
satellite derived measurement of the radiative character of energy radiated from the warmer earth surface to cooler space. This measurement provides information on cloud-top temperature which can be used to estimate tropical precipitation amounts ...
It is invisible and often activates the production of melanin in human skin as well as vitamin D. In excessive amounts, however, it can damage skin tissue (sunburn) and even cause skin cancer.
As the earth moves and spins it is tilted in one direction at an angle of 23 degrees. It stays tilted all the time as it orbits the sun, so that each area of earth receives different amounts of the sun's energy at different times of the year.
and display power provided by the Advanced Weather Interactive Processing System (AWIPS) installed at the National Weather Service Forecast Offices, the Garcia Method has become a favority tool of their meteorologists in forecasting snowfall amounts ...
