Reference excerpt

Leslie R. Lemon (January 19, 1947 – May 29, 2020) was an American meteorologist bridging research and forecasting with expertise in weather radar, particularly regarding severe convective storms. Lemon was, along with Charles A. Doswell III, a seminal contributor to the modern conception of the supercell convective storm which was first identified by Keith Browning, and he developed the Lemon technique to estimate updraft strength and thunderstorm organization (in highly sheared environments) also as a continuation of Browning's work.

Early life Lemon's interest in severe storms was triggered in earnest after he witnessed the F5 Ruskin Heights tornado on May 20, 1957, which caused light damage to his family's home and severe damage very nearby. Lemon studied meteorology at the University of Kansas (KU) and the University of Oklahoma (OU), graduating with a B.S. from OU in 1970.

Career Lemon embarked on graduate school studies but it was during the Vietnam era so he wasn't able to continue, and he instead joined the NOAA Commissioned Corps. Afterward, in addition to developing the Lemon technique at the Techniques Development Unit (TDU) of the National Severe Storms Forecast Center (NSSFC) and his work on the supercell storm, Lemon was a major developer of the WSR-88D or "NEXRAD". In 1976 NOAA bestowed a Special Achievement Award for his co-discovery of tornado vortex signature (TVS). In tandem with developing new radar analysis concepts Lemon was early in integrating mesonet data from NSSL to connect what was occurring at the surface with radar depictions. He later taught widely on the subjects of radar and severe convective storms throughout the United States and internationally, leaving the public sector to work at various companies. At Lockheed Martin, Lemon was a key developer of its microburst prediction radar. Lemon also worked at Unisys and other companies during his career and operated a forensic and consulting meteorology company. Lemon was president of the National Weather Association (NWA) in 2001 and served on a National Academy of Sciences National Research Council (NAS NRC) committee on "Weather Radar Technology Beyond NEXRAD" that same year. He was also an expert storm damage surveyor and surveyed the first documented tornado in Romania while doing radar work there.

Death Lemon died on May 29, 2020, at age 73.

Worked examples

Example 1 — a first encounter with Leslie R. Lemon

Start with the simplest possible case. Write down what Leslie R. Lemon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Leslie R. Lemon before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Leslie R. Lemon ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Leslie R. Lemon

In research: Leslie R. Lemon appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Leslie R. Lemon in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Leslie R. Lemon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, 2020 deaths, American meteorologists, so understanding it makes those chapters shorter.
In everyday life: Look for Leslie R. Lemon outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
