A brief discussion of the main causes of latitudinal inequality in the distribution of solar radiation at the earth's surface, and a diagram of the radiation budget.
Definitions of the physical and thermodynamic properties of water vapor in the atmosphere and useful formulas for estimating heat of vaporization, air and water vapor density, saturation vapor pressure, dewpoint, specific humidity, relative humidity, and maximum precipitable water
A brief explanation of lapse rates and their control of air-mass stability, with diagrams.
Diagrams showing the characteristic of fronts and the development of a wave cyclone.
This document describes step-by-step how to determine the equations of straight lines plotted on linear, semi-log, and log-log graph paper. Includes diagrams and examples.
A short summary of the basic statistical methods used to describe hydrologic data: measures of central tendency (means), variability (standard deviation), asymmetry (skewness), and confidence intervals.
A description of how to compute and plot the frequency of annual precipitation values at a site.
How to compile, compute, and plot 1) flood frequency data, 2) flow duration data; and 3) at-a-station hydraulic geometry. Includes a short section on regionalization of flow-duration curves.
A short derivation of Penman's approach to computation of evaporation and potential evapotranspiration from net radiation, temperature, and vapor pressure.
