10/6/10Aim: What is a Field?

Do Now: R&H p.26, A&E #31-34

HW – Finish lab


Field any region of the environment where a measurement can be taken at every location

Field – any region of the environment where a measurement can be taken at every location

Field Value – whatever aspect of the field that you choose to measure. Ex. Temp, pressure, density, rainfall, snowfall, elevation, etc.

Isolines – lines that connect points of equal field value.

Field Map- A map made of isolines that show a pattern of data and allow us to predict any location on the map.

Interval- the value of increase/decrease for each isoline.


Gradient how fast change is occurring very similar to rate of change

Gradient- how fast change is occurring, very similar to Rate of Change.

Gradient = change in field value

change in distance

  • The closer spaced your isolines are the greater the gradient between the two locations.

  • Field maps generally have energy that flows from a source (highest value) to a sink (lowest value).


Types of isolines and field maps

Types of Isolines and Field Maps

  • Isotherm- connects points of equal temperature.

  • Isobar- connects points of equal air pressure.

  • Isoyet- connects points of equal rainfall.

  • Contour line- connects points of equal elevation.
