kona cyclone
Very LowTechnical / Regional / Meteorological
Definition
Meaning
A type of subtropical cyclone that forms during the winter months in the Central Pacific Ocean, to the west of Hawaii, bringing strong, moisture-laden winds and heavy rainfall from the south or southeast.
More broadly, any significant storm system in the Hawaiian region associated with southerly or southeasterly winds that reverse the typical northeast trade wind pattern, often leading to prolonged periods of unstable, wet, and stormy weather. In meteorology, it refers to a specific synoptic-scale pattern of low-pressure circulation.
Linguistics
Semantic Notes
The term is highly specific to Hawaiian and Central Pacific meteorology. It is not a generic term for any Pacific storm but denotes a specific weather pattern characterized by wind direction reversal. 'Kona' is a Hawaiian word meaning 'leeward'.
Dialectal Variation
British vs American Usage
Differences
The term is almost exclusively used in American English, specifically within the context of Hawaiian and US Pacific meteorology. British English would likely use a more generic description like 'subtropical storm' or 'Hawaiian storm system'.
Connotations
In US/Hawaiian usage, it connotes a specific, disruptive weather event with localised impacts. It has no established connotation in British English.
Frequency
Virtually never used in British English. Its frequency in American English is still low, confined to weather reports and discussions in or about Hawaii.

Usage
Context Usage
Business
Used in business contexts related to Hawaiian tourism, agriculture, or logistics to discuss weather-related disruptions. (e.g., 'The Kona cyclone delayed cargo shipments to the outer islands.')
Academic
Used in meteorological, climatological, and environmental science papers focusing on Pacific weather patterns.
Everyday
Used in everyday conversation primarily by residents of Hawaii when discussing significant winter weather. Unfamiliar to most other English speakers.
Technical
Used in technical weather forecasts, marine warnings, and atmospheric science to describe a specific synoptic setup with a cold-core low and associated convergent southerly flow.
Examples
By Part of Speech
verb
American English
- The system is expected to kona-cyclone by the weekend. (rare, informal technical)
adjective
American English
- Kona-cyclone conditions are expected to persist for 48 hours.
- We are in a Kona-cyclone pattern.
Examples
By CEFR Level
- The weather is bad because of a Kona cyclone.
- A Kona cyclone can bring a lot of rain to the islands.
- Unlike hurricanes, a Kona cyclone derives its energy from the difference in air masses rather than warm ocean water.
- The forecast model predicts the upper-level trough will trigger the development of a classic Kona cyclone southwest of Kauai.
Learning
Memory Aids
Mnemonic
Think: 'Kona' sounds like 'corner' – these cyclones come from a different corner (the south) than the usual trade winds, cornering Hawaii with bad weather.
Conceptual Metaphor
A Kona cyclone is a REVERSAL or an INVERSION of the normal state (the steady trade winds).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'Kona' as a generic location; it is a borrowed Hawaiian term with a specific meteorological meaning.
- Do not confuse with 'ураган' (hurricane) or 'тайфун' (typhoon); a Kona cyclone is generally less intense but more prolonged.
- The word 'cyclone' here does not imply the devastating power of a 'циклон' in a Russian weather report; it's a technical term for a low-pressure system.
Common Mistakes
- Using 'Kona cyclone' to refer to any storm near Hawaii.
- Spelling 'Kona' as 'Cona' or 'Konia'.
- Pronouncing 'Kona' with a short 'o' (as in 'cot') instead of a long 'o' (as in 'cone').
- Confusing it with a hurricane, which is a warm-core system and occurs in a different season.

FAQ
Frequently Asked Questions
No. A hurricane is a warm-core tropical cyclone. A Kona cyclone is a cold-core subtropical cyclone, typically larger, less intense in terms of peak winds, but capable of producing widespread heavy rain and surf over a longer period.
They are primarily a winter phenomenon, occurring from October through April, with peak frequency in the winter months.
'Kona' is the Hawaiian word for 'leeward.' These storms bring winds from the leeward (south) direction, opposite to the typical windward (northeast) trade winds.
While the term is specific to Hawaii, the meteorological pattern can occur in other subtropical regions. Similar systems are sometimes called 'subtropical lows' or 'cold-core lows' elsewhere.
