Why did Simpson study clouds?

At the time, nobody thought clouds were a big part of what drives the weather; they were more the result of weather, not the cause. “So I was interested in clouds for just themselves because they were fascinating,” explains Simpson.

Which cloud did Dr Joanne Simpson refer to as hot towers?

cumulonimbus clouds
In the late 1950s, Simpson and her former Ph. D. advisor, Riehl, turned meteorology on its ear when they showed that heat generated by the condensation of water within tall, anvil-shaped, cumulonimbus clouds called “hot towers” provides the energy needed to keep the Hadley circulation and the trade winds running.

When was Joanne Simpson born?

What was Joanne Simpson’s legacy?

Joanne was the first female meteorologist to earn a doctorate, developed the first scientific model of clouds, discovered what keeps hurricanes whirling forward and revealed what drives the atmospheric currents in the tropics.

What are hot towers or chimney clouds?

A “hot tower” is a tall cumulonimbus cloud that reaches at least to the top of the troposphere, the lowest layer of the atmosphere. It extends approximately 9 miles/14.5 km high in the tropics. These towers are called “hot” because they rise to such altitude due to the large amount of latent heat.

How do these hot tower clouds form?

A hot tower is a tropical cumulonimbus cloud that reaches out of the lowest layer of the atmosphere, the troposphere, and into the stratosphere. These formations are called “hot” because of the large amount of latent heat released as water vapor condenses into liquid and freezes into ice within the cloud.

What is a very large hot tower called?

According to a NASA press release in 2004, When these tall clouds, called “hot towers,” are present, they double the chance that a hurricane will gather strength within hours… Warm air rises, and these towers are called “hot” because they rise very high due to a large amount of heat, called latent heat.

Who was Joanne Simpson’s Ph.D advisor at NASA?

Simpson struggled on with student loans. After completing a course with Herbert Riehl on tropical meteorology, she decided to concentrate on tropical cumulous clouds and asked Riehl if he would be her Ph.D. advisor. To her and everyone’s surprise he agreed.

Where did Joanne Simpson go to graduate school?

Simpson received both her undergraduate and graduate degrees from the University of Chicago, and did post-doctoral work at Dartmouth College.

Who was Joanne Simpson’s former husband at MIT?

Her former husband Willem Van Rensselaer Malkus (1923-2016) was a professor of applied mathematics at MIT. Simpson died March 4, 2010 in Washington D.C., surrounded by her family. ^ “Welcome to the University of Chicago College Report Online”.

What did Joanne Simpson do at Woods Hole?

To her and everyone’s surprise he agreed. Simpson’s early research at Woods Hole involved filming clouds on long flights between islands in the tropical Pacific. She then drew intricate maps of cloud formations, revealing for the first time patterns that are now routinely shown by satellites.
