Temporal distribution of earthquakes, especially so-called characteristic earthquakes recurring on a specific fault or fault segment, often represented by a renewal process. It is defined as a series of events in which interevent times are independently and identically distributed.

What is temporal distribution of rainfall?
The temporal rainfall distribution is usually expressed as the rainfall intensity distribution in time (a hyetograph) and, for a given rainfall depth and duration, it may be further characterized by the peak intensity and its timing.
What is a distribution in physics?
In molecular kinetic theory in physics, a system’s distribution function is a function of seven variables, , which gives the number of particles per unit volume in single-particle phase space. It is the number of particles per unit volume having approximately the velocity near the position and time .
What is quantum distribution function?
The quantum kinetic equation is in the slowly-varying center-of-mass coordinate approximation expressed in terms of the Wigner function. The collision integral is simplified by means of the generalized Kadanoff—Baym ansatz formulated in a gauge invariant way which respects causality.
What is meant by spatial and temporal distribution?
Spatial refers to space. Temporal refers to time. Spatiotemporal, or spatial temporal, is used in data analysis when data is collected across both space and time. It describes a phenomenon in a certain location and time — for example, shipping movements across a geographic area over time (see above example image).
What are the 3 types of spatial distribution?
Spatial distribution can be measured as the density of the population in a given area. The three main types of population spatial distribution are uniform, clumped, and random. Examples of the types of spatial distribution: uniform, random, and clumped.
What are the variations of distribution of rainfall?
As per Climatology, rainfall may be classified into three main types – the conventional, orographic or relief, and the cyclonic or frontal.
What is spatial rainfall?
The influence of the spatial rainfall variability on the results of hydrological modelling applications is studied. It involves the quantification and stochastic description of the rainfall input errors for catchment rainfall-runoff and urban drainage models.
What do you mean by Hyetograph?
Definition of hyetograph 1 : a chart showing average annual rainfall.
How many types of distribution are there?
Based on the types of data we deal with, we have two types of distribution functions. For discrete data, we have discrete distributions; and for continuous data, we have continuous distributions.
What is distribution and example?
Distribution is defined as the process of getting goods to consumers. An example of distribution is rice being shipped from Asia to the United States.
What is Bose Einstein distribution law?
The Bose-Einstein distribution describes the statistical behavior of integer spin particles (bosons). At low temperatures, bosons can behave very differently than fermions because an unlimited number of them can collect into the same energy state, a phenomenon called “condensation”.
What is Maxwell distribution law?
The distribution function implies that the probability dP that any individual molecule has an energy between E and E + dE is given by dP = fM–BdE. The total energy (E) usually is composed of several individual parts, each corresponding to a different degree of freedom of the system.
What is Maxwell Boltzmann distribution law?
The Maxwell–Boltzmann distribution concerns the distribution of an amount of energy between identical but distinguishable particles. It represents the probability for the distribution of the states in a system having different energies. A special case is the so-called Maxwell distribution law of molecular velocities.
What is the difference between spatial distribution and spatial processes?
In this case, the spatial distribution is the Irish-American population in the United States, and the spatial process was the series of physical, environmental and human events that led to this change.
What is temporal and spatial coherence?
Spatial coherence describes the correlation (or predictable relationship) between waves at different points in space, either lateral or longitudinal. Temporal coherence describes the correlation between waves observed at different moments in time.
What causes spatial distribution?
Spatial distribution of individuals belonging to one population or of populations belonging to one metapopulation are affected by resource availability and habitat fragmentation, and are created by natural factors such as dispersal, migration, dispersion, and human-caused factors such as habitat fragmentation.
How do you explain spatial distribution?
A spatial distribution in statistics is the arrangement of a phenomenon across the Earth’s surface and a graphical display of such an arrangement is an important tool in geographical and environmental statistics.
What is spatial distribution example?
For example, the spatial distribution pattern definition can be used to examine how green spaces (such as parks and environmentally-friendly sites) are distributed throughout a city to promote the production of inner-city health.
How do you find spatial distribution?
To analyze the spatial distribution of attribute values (not features itself, but certain attribute values), you can divide (weigh) the values by distance to neighbors and create a frequency distribution. You can then compare that against a uniform or random distribution.
What determines the spatial distribution of rainfall?
The average distribution of precipitation provides essential input for understanding the hydrological process. The role of complex topography in mountainous basins makes the spatial distribution of precipitation different than the plain areas.
What affects rainfall distribution?
Moisture supply to the atmosphere is the main factor in determining the amount of rainfall in any region. Equatorial and rest of the tropical region have highest evaporation and hence highest supply of moisture. Coastal areas have more moisture than interior parts of continents.
Why is there an uneven distribution of rainfall in the world?
Note: The belts of converging-ascending air flow, air temperature, moisture-bearing winds, ocean waves, distance inland from the coast, and mountain ranges are all factors that influence the distribution of rainfall over the earth’s surface.
What do you understand by spatial and temporal variability in rainfall?
The average annual rainfall is about 125 cm, but it has great spatial and temporal variations. Temporal variation: The distribution of rainfall varies temporally as per an annual cycle of seasons. The meteorologists recognise four seasons.
What is temporal variation?
Ecological temporal variability can be defined as the frequency and magnitude of fluctuations in ecosystem structure (eg standing stocks of resources, species abundance) or ecosystem function (eg production, decomposition rate).
