PRECIPITATION PART 2 Flashcards
CHARACTHERISTICS OF PRECIPITATION
Intensity
Frequency
Duration
It refers to the amount of precipitation that falls during a specific time period, typically measured in millimeters or inches per hour.
INTENSITY
Higher intensity precipitation events are often associated with more extreme weather conditions, such as
thunderstorms
hurricanes
heavy snowfall
It refers to how often precipitation events of a certain intensity occur over a specific time period, typically measured in terms of the number of events per year.
FREQUENCY
can be used to identify the probability of extreme precipitation events occurring in a given region, which can help inform planning and management decisions.
Frequency analysis
It refers to how long a precipitation event lasts, typically measured in hours.
DURATION
Longer-duration precipitation events can lead to more widespread and sustained impacts, such as
flooding or erosion
PRECIPITATION PATTERNS
Spatial Distribution
Temporal Distribution
refers to the pattern of where precipitation falls over a specific area.
Spatial Distribution
Spatial Distribution can be influenced
by a variety of factors, such as
Topography
Distance from water sources
Prevailing wind patterns.
characterized by intense, short-duration storms that are highly variable in space and time.
Localized Convective
Precipitation
precipitation refers to the pattern of when precipitation occurs over a specific time period, such as a day, a month, or a year.
Temporal Distribution
Temporal Distribution can be influenced by
Seasonal and Climatic Factors
Weather Patterns (fronts and atmospheric disturbances)
