Exercise Listing 2.1: Calculate Circle Area
Write a simple application that computes the area of a circle, knowing that π = 3.14159 and radius = 20.
ComputeArea.java
public class ComputeArea {
public static void main(String[] args) {
double radius; // Declare radius
double area; // Declare area
// Assign a radius
radius = 20; // radius is now 20
// Compute area
area = radius * radius * 3.14159;
// Display results

Aurora
An aurora is a glow that appears in the night sky, usually in polar regions. In the Northern Hemisphere, it is known as the Aurora Borealis, and in the Southern Hemisphere, it is known as the Aurora Australis.
Origin of the Aurora Borealis or Polaris
An aurora originates when a solar mass ejection collides with the north and south poles of the Earth’s magnetosphere, which is projected to the ionosphere.
Variation of Temperatures
- Diurnal Variation: The change in temperature between day and night
Aviation and Snow Sports Weather: Clouds, Visibility, and Hazards
Flying Weather: Clouds and Ceiling
Normal Clouds:
- Convective/Cumuliform clouds (Cu): Look like stacked cotton balls, associated with updrafts.
-
Layer/Stratiform clouds (St): Look like sheets/blankets, extending horizontally.
- Nimbostratus: Precipitating.
- Stratus: Not precipitating.
From increasing height: stratus/nimbostratus, altostratus/cumulus, cirrostratus/cumulus, cirrus.
Special Clouds:
-
Clouds in unstable air aloft:
- Castellanus: Small castle turrets, indicate potential thunderstorms.
- Billow (K-
Evapotranspiration & Cloud Types: Measurement Methods
Actual Evapotranspiration (ETR)
Actual evapotranspiration (ETR) refers to evapotranspiration under real environmental conditions, considering variations in soil moisture and incomplete cover.
Methods for Determining Potential Evapotranspiration
Experimental Methods
Experimental methods are conducted in agricultural experiment stations, either in test plots or in lysimeters.
- Test Plots: Test plots involve preparing plots of land with established vegetation cover. The test controls all moisture inputs

Climate: Key Terms and Definitions
Anticyclone
Anticyclone: An atmospheric center of action with a pressure greater than 1013 mbar, which is the mean pressure at sea level.
Aridity
Aridity: Synonymous with scarcity, defined as water shortages resulting from the relationship between rainfall, vegetation, and temperature.
Cierzo
Cierzo: A local term in the Ebro Valley for a northwest wind with a cold, gusty, and dry character. It is channeled through the valley, reaching great speeds.
Jet Stream
