What are two sources of moisture for a water budget?
precipitation and potential evapotranspiration
Which condition most likely exists when precipitation is greater than potential evapotranspiration and soil water storage is at the maximum?
run off
How do you calculate climatic water balance?
The Climatic Water Balance (CWB) results from the Precipitation (actual) minus Evapotranspiration (potential) Climatic Water Balance is actual Precipitation minus potential Evapotranspiration CWB=P-PET Exp: PET= 16.09 mm/month P= 46 mm/month CWB=46-16.09 =29.91 mm/month
Transfer of moisture from land to air?
Evapotranspiration
Which is the primary energy source for evapotranspiration?
sunlight
What does D mean on a water budget?
D -deficit Ea- actual evapotranspiration St-storage S-surplus P-precipitation Ep- potential evapotranspiration P-Ep- Precipitation - Potential Evapotranspiration
What is the potential evapotranspiration ratio?
The potential evapotranspiration concept was first introduced in the late 1940s and 50s by Penman and it is defined as " the amount of water transpired in a given time by a short green crop , completely shading the ground , of uniform height and with adequate water status in the soil profile ". Note that in the definition of potential evapotranspiration , the evapotranspiration rate is not related to a specific crop .
What causes potential evapotranspiration to change?
Average surface temperature
What are two sources of moisture for a water budget?
precipitation and potential evapotranspiration
What causes the potential evapotranspiration to vary from month to month?
Temperature change within the months
What is a climate ratio?
Climate ratio is used to describe the moisture side of climate. It compares the precipitation (P) with the potential evapotranspiration (Ep) for a region. One way to do this is to express the relationship between them as a ratio using the formula: Climate ratio = P / Ep When the potential evaporation is greater than yearly precipitation, this ratio is less than 1. When precipitation is greater than evapotranspiration, the ratio is greater than 1. P: precipitation (in mm) or the amount of moisture available for evapotranspiration, evapotranspiration is the combined process of evaporation and plant respiration. Ep: potential evapotranspiration (in mm) or the amount of moisture needed for evapotranspiration. This value increases as temperature and plant life increase. The climate ratios are used to determine climate type: P/Ep: Less than 0.4: arid climate 0.4 - 0.8: semiarid climate 0.8 - 1.2: subhumid climate Greater than 1.2: humid climate Source: NOAA
Which condition most likely exists when precipitation is greater than potential evapotranspiration and soil water storage is at the maximum?
run off

Does this have the highest ozone depletion potential?
CFC's have highest potential. They react with ozone and destroy it.
What metal has the highest negative potential?
Lithium has the highest negative potential of -3.045 volts
How are dry climate regions identified?
In The Online World It Says That, "They are usually identified by having a low precipitation to potential evapotranspiration (P/PET) ratio."
