MetVUW

MetVUW is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand MetVUW rather than just read about it. In short: Metvuw Weather and Climate service is run by James McGregor. The site was formerly associated with Victoria University of Wellington (hence the VUW acronym), but is now run independently.

Key takeaways

MetVUW belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect MetVUW to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MetVUW from memory before moving on to harder problems.

Reference excerpt

Metvuw Weather and Climate service is run by James McGregor. The site was formerly associated with Victoria University of Wellington (hence the VUW acronym), but is now run independently. Much of the weather content and forecast material is available directly from the website, free. A range of different weather information is available, as different pages, under the following headings.

Metvuw home Featuring updates advice about the service, and 'photo of the day' as well as links to previous photos of the day. Many images of quirky and unusual weather-related phenomena are to be found, especially clouds of the Mammatus variety.

Satellite imagery 9 panels of monochrome satellite derived cloud pictures are shown, in 3 hour intervals, ending in current time slot. Images can be enlarged. Data provided by MetService, Image enhancement by Metvuw, Himawari satellite data courtesy of Japanese Meteorological Agency.

Weather radar 3 panels each showing 9 locations throughout New Zealand, at 3 hour intervals, ending in current time slot. Colour coding is derived from 'reflectivity' (DBz). Images can be enlarged. Data provided by MetService, Image enhancement by Metvuw.

Radiosondes (weather balloons) measuring upper air temperatures and winds are routinely launched from five stations around New Zealand. At Whenuapai, Paraparaumu and Invercargill they are launched at 1100 and 2300 NZT. At Raoul Island they are launched daily at 1100 NZT. The upper air data are displayed on tephigrams.

Forecast charts A large range between 1 and 10 day forecasts are available, delivering 4 and 40 images, respectively, spaced at +6 hour intervals, beginning with the forecast time. These weather forecast charts are generated by software written and maintained by James McGregor. The data used is obtained from the United States National Weather Service. These charts are updated approximately every 6 hours and provide forecasts up to 240h ahead of the time they were issued.

Current NZ weather Selections are available for temperature, precipitation, pressure and wind. A national map is shown with data at each of many significant locations.

Ocean weather Data is available for each of 7 seas/oceans. Up to 10-day thumbnails deliver 40 images, spaced at +6 hour intervals, beginning with the forecast time.

Worked examples

Example 1 — a first encounter with MetVUW

Start with the simplest possible case. Write down what MetVUW claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 MetVUW 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 MetVUW 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 MetVUW

In research: MetVUW appears in 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 MetVUW 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: MetVUW is common in secondary-school and first-year university syllabi. It links to neighbouring topics Meteorological research institutes, Wellington City, so understanding it makes those chapters shorter.
In everyday life: Look for MetVUW 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.

Frequently asked questions

What is MetVUW in simple terms?

Metvuw Weather and Climate service is run by James McGregor. The site was formerly associated with Victoria University of Wellington (hence the VUW acronym), but is now run independently.

Why does MetVUW matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study MetVUW?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on MetVUW.
