Tropical Warm Pool International Cloud ExperimentTWP-ICE • How do the storms over Darwin happen? • What is in the clouds over Darwin? • Are we taking good measurements?
The Tropical Warm Pool - International Cloud Experiment TWP-ICE
Why was Darwin chosen for TWP-ICE? • Australian Monsoon • Wet season (lots of clouds!) • Atmospheric Radiation and Measurement site (ARM) • Instruments available • Climate Record TWP-ICE location
What was Lis doing in Darwin? Plotting Airplane Tracks Mapping Cirrus Clouds Learning about research Creating Graphics
Why do meteorologists care about clouds (and why should you care)? • Roles of clouds • Source of precipitation • Reflect sunlight (create shadows) cools the Earth’s surface • Can ALSO heat the Earth’s surface • Come in interesting shapes
The journey of a cirrus cloud named Icy • Let’s take a journey and follow Icy! • Where did Icy form? • What is Icy carrying? • Where did the journey start? • Where has Icy been on the journey and where is Icy going? Icy
E. Cohen E. Cohen Cloud Characteristics • Cirrus • Fiber or Hair • Cumulus • Heaped or Piled
E. Cohen E. Cohen Cloud Characteristics • Stratus • Sheet or Layer • Nimbus • Rain Making
E. Cohen E. Cohen Is Icy outside right now? • CIRRUS CLOUDS • Usually appear white, except for sunrise/set • Usually thin and composed of almost all ice crystals
E. Cohen Cloud LevelsHigh Clouds • CIRRUS • CIRROSTRATUS • CIRROCUMULUS Photo: WBZ-Mos
Where did Icy come from? Blown off ice crystals from a cumulonimbus cloud Anvil Ice crystals formed from lifted air Anvil
What is Icy bringing on the journey? Icy has been carrying • Many Gases • Many small particles • Salt • Dust • Ice crystals!
From Korolev and Isaac, 2005 Icy is made up of ice crystals! Is it easy to measure ice crystals?
How did we measure Icy? Weather balloons Aircraft Instrument Stations and Boat
Weather balloon (Radiosonde) Measures temperature, humidity, wind speed, and wind direction all the way up!
Airplanes! Dornier Dimona
High Flying Airplanes Proteus Egrett
Where did Icy come from? Cirrus Cloud Tracking Follow the black box. Can you follow the shapes in box?
