METEO 3 Lab 1 9/4/19
TA: Rachel Gutierrez Office: 412 Walker Office Hour: Thursdays 10am – 11am or by appointment Email: rachel.tstorm@gmail.com Labs are due on Fridays at the beginning of class
Tips for Labs • Bring a hard copy of the lab • Come ready with questions • Bring the textbook • Show all work for problems (and all units!) • Work with other students to solve problems but don’t copy each other • Don’t wait until the last minute • Come to office hours
Problem 1.4: Temperature Conversions • What is absolute zero? • In K? • Convert to oC • Convert to oF • Use C F and F C conversions to find out what’s special about -40oF
Problem 1.7: Isoplething • What’s an isopleth? • Line of constant __________ • Isobar: line of constant pressure • Isotherm: line of constant temperature • Isodrosotherm: line of constant dewpoint • Isoplething is like connecting the dots • To check your isopleths: does your line fit between the surrounding numbers correctly? • Don’t isopleth where you don’t have data • Don’t cross your isopleths • Label your isopleths • Isopleths can form closed loops
Problem 2.1: Radiation • Stefan-Boltzmann Law: • E = σT4 • E: energy emitted per unit area (W m-2) • σ: 5.67 x 10-8 W m-2 K-4 • T: temperature (K) • a) E sun / E earth • b) Find E for both Venus and Mars • c) Thought question – why do you think Venus has a high temperature? What is unique about the atmosphere?
Problem 2.2 and 2.6: Radiation • Wien’s Law: • Wavelength of Maximum Emission = • 2.2: Find wavelength of max emission for: • Sun • Earth • Human body • 2.6: This problem discusses energy … so use Stefan-Boltzmann Law! • What happens when you emit more than you absorb? • What happens when you absorb more than you emit?
