How is Math Applied in the Weather There are lots of ways for Math to be applied to the weather. Temperature Conversion By: Princeton G. Luz Volume of Precipitation Number Lines Example:

Given -5°C, 10°C, 4°C, -2°C, 0°C Units of Measurement for Temperature: Celsius

Fahrenheit

Kelvin To convert Celsius to Fahrenheit:

F = ( C x 1.8) + 32 To convert Fahrenheit to Celsius:

C = ( F - 32 ) / 1.8 To convert Celsius to Kelvin:

K = C + 273.15 To convert Kelvin to Celsius:

C = K - 273.15 To convert Fahrenheit to Kelvin:

K = ( (F - 32 ) / 1.8 ) + 273.15 To convert Kelvin to Fahrenheit:

F = ( ( K- 273.15 ) x 1.8 ) + 32 You can find the volume of precipitate by multiplying the amount or depth of rainfall and the area it covers. Volume= Depth x Area Application of Integers in Weather Forecasts Example: 1. If the temperature changed from 19° to 13°C for Monday. Then (13 - 19) = -6. This means that there is a decrease of 6°C.

2. If the temperature changed from 20°C to 13°C on Wednesday. Then (13 - 20) = -7.

This means that there is a decrease of 7°C.

3. If the temperature changed from 23°C to 13C on Thursday. Then (13 - 23) = -10.

This means that there is a decrease of 10°C. Speed of Typhoon You can get the speed of a typhoon given the amount of time it takes for it to travel a certain distance. Speed = Distance / Time Example: C = 5

F = ( 5 x 1.8 ) + 32

F = 9 + 32

F= 41 Example: F = 41

C =(41 - 32) /1.8

C = 9/1.8

C = 5 Example C = 5

K = 5 + 273.15

K = 278.15 Example K = 278.15

C = 278.15 - 273.15

C = 5 Example F = 41

K = ((41 - 32) /1.8) + 273.15

K = (9/1.8) + 273.15

K = 5 + 273.15

K = 278.15 Example K = 278.15

F = (( 278.15 - 273.15) x 1.8) +32

F = ( 5 x 1.8 ) + 32

F = 9 + 32

F= 41 Example: Timmy's house had a flood, His house has an area of 50m and the depth was 5m. What is the volume of the flood? Solution

V = ( 5m x 50m )

V = 250m 2 2 2 3 Example: Timmy saw a typhoon on the news. It has traveled 240km in 2 hours. What is the speed of the typhoon? Solution

S = 240km/2 hours

S = 120kph Temperature - the degree or amount of heat present in the atmosphere. Sources http://www.mathsisfun.com/number-line.html
