El Niño, a complex weather phenomenon, has been a subject of interest for researchers and scientists worldwide. One of the key aspects of El Niño is its impact on global climate patterns. In this write-up, we will explore the concept of El Niño, its effects, and discuss a specific PDF document titled "El Niño Normal Illingworth".
Let SST_observed be the monthly sea surface temperature at [170°W, 5°S]. Let SST_clim be the 30-year climatological mean for that month. A traditional anomaly is A = SST_obs - SST_clim. However, if a linear warming trend (T) exists, the Illingworth Normalized Anomaly (INA) is:
To understand the book, you must first understand the man behind it. Dr. Ronald Stanley Illingworth (1909-1990) was a giant in the field of pediatrics. His work revolutionized how the medical community and parents understood child development. el nino normal illingworth pdf
| Feature | Normal Year | El Niño Year | |--------|------------|--------------| | | Strong (east to west) | Weak or reversed | | Warm water location | Western Pacific (Indonesia) | Central & Eastern Pacific | | Cold water upwelling | Strong off South America | Suppressed or absent | | Rainfall in Indonesia | Heavy | Drought | | Rainfall in Peru | Dry | Floods | | Thermocline slope | Steep (west deep, east shallow) | Flat |
Heavy rainfall and convection are typically confined to the western Pacific, while the eastern Pacific remains relatively dry. 2. El Niño Conditions (Warm Phase) El Niño, a complex weather phenomenon, has been
By defining the massive statistical variance of normal development, Illingworth saved generations of parents from unnecessary anxiety and stopped doctors from over-diagnosing normal developmental lags as pathologies. Part 2: The Climatological "Normal" vs. El Niño
: This book is unrelated to the El Niño climate phenomenon , which involves periodic ocean warming in the Pacific. Understanding El Niño - NOAA Let SST_observed be the monthly sea surface temperature
In the eastern equatorial Pacific—particularly in the (spanning 5°N–5°S and 150°W–90°W)—SST anomalies exhibit significant positive skewness .
El Niño events have significant impacts on global climate patterns, affecting agriculture, fisheries, and human populations. Some of the notable impacts include:
Under neutral or standard conditions, the tropical Pacific behaves like a well-balanced thermal engine:
Below is a to understanding this topic, which is what you would typically find in such a PDF or textbook extract.
