Mathematical Prediction Models for Hurricane Jimena

 

 

 

 

 

The National Weather Service (NWS) runs numerical weather models that generate guidance information
for weather forecasters.  This IBM supercomputer (below) at the NWS can make
more than 450 billion calculations per second.


 

 

Several different prediction models are used to predict atmospheric phenomena and they
don't always agree.  Take, for example, this image of model predictions
for the track of hurricane Rita:

Models and Scientific Theory

Thoughts from J.C. Evans of George Mason University

 

Science Seeks to Minimize Bias to avoid
the unforseen, such as the Challenger Disaster

The Bay Delta Model

B. Foundational Laws

Conservation of Mass

Open Mass System Example:
The Oceanside Littoral Cell

First Energy Law (energy conservation)

Einstein, from L.A. Times 1/29/07

The First Law of Thermodynamics

"In a system of constant mass, energy is neither created nor destroyed,

but is transformed from one form to another

whenever work is performed."

Second Energy Law (entropy nonconservation)

Atom Animation

Listen to "Entropy"

Entropy, Disorder and "Times Arrow"

Entropy is a measure of the inability to perform work
Irreversible processes in nature cause a loss of some of the ability
to perform work, or an increase in entropy of the universe.
The entropy of the universe, like "Times Arrow", is
continuously increasing.
Increase in entropy = Increase in disorder

Notice that the label states the amount of chemical energy stored within one
serving of the cheese and is expressed in kJ.

What is GIS?

What is the Future of Cartography and GIS?
An interactive Internet GIService built on a fully distributed
architecture
.  No need for expensive GIS software.  No need to
download GIS data.  Obtain your data, build your map, and perform
your analysis using a standard web browser from your home!
Check out these examples of Internet GIS and Web-Mapping...

A foundational understanding of earth-sun
relationships will provide a basis for gaining
knowledge about the spatial and seasonal variations
of solar insolation receipt on earth.

C. Solar Declination
Defined as the line of latitude over which the sun
is directly overhead on any given day.  Solar declination
changes day to day due to the 4 main characteristics
of the Earth's revolution around the Sun.
What are the 4 main characteristics?
