About the genus · Handroanthus

Handroanthus is a genus of flowering plants in the family Bignoniaceae. It consists of 30 species of trees, known in Latin America by the common names poui, pau d'arco, or ipê. The latter sometimes appears as epay or simply ipe (unaccented) in English. More on Wikipedia ›

Rain rule: a sharp rainy season, November to April at the habitat (not shifted); the temperature curve is flat (2.4 °C of range), so no growing season is inferred. Habitat rain 1053 mm a year, wettest March at 167 mm, driest August at 22 mm (habitat calendar, southern hemisphere). Open sky over the habitat: 29 to 38 mol/m²/day. Cold floor 15.3 °C (1st-percentile habitat night, NASA POWER).

Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

Cultivation

Its year Rain rule: a sharp rainy season, November to April at the habitat (not shifted); the temperature curve is flat (2.4 °C of range), so no growing season is inferred.

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads a sharp season: 70% of the year's rain (748 mm of 1053 mm) falls in November to April. The temperature curve is flat, 2.4 °C between the warmest and coldest month, so the growing-season rule does not infer a growing season from it. Months are the habitat's, southern hemisphere, within 10° of the equator; with no thermal season there there is no season to reverse, so they are not shifted for a collection elsewhere.

Read from the median year of CHELSA monthly rainfall and mean temperature across the envelope cells: the rain rule takes the smallest set of months carrying 70% of the rain and calls it winter when its mean is more than half a degree below the year's, summer when more than that above, and neither in between; the temperature rule, used only under 120 mm, names the cooler six months when they are at least a degree cooler than the other six. Months are shifted for the other hemisphere only where the temperature curve gives a season to reverse. A reading of the curves, not an observation of the plant.

1053 mm a year at the habitat, 748 mm of it November to April. Wettest month March at 167 mm, driest August at 22 mm. Across the envelope cells the year's total runs 663 mm to 2009 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, southern hemisphere).

Open sky over the habitat: 29 to 38 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA; the lowest 10th-percentile month across the cells is 21, the highest 90th-percentile month 45).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is 15.3 °C, the absolute minimum 9.9 °C, no frost in 44 years (NASA POWER daily minima). Warmest: the 99th-percentile day is 42.0 °C. Monthly means: coldest night 18.5 °C in July (across the envelope cells 11.8 °C to 23.6 °C), warmest day 29.5 °C in February (median year across the envelope cells, CHELSA). Cold floor: 15.3 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 341 grid cells holding the 414 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 1426:1583 (18.675, -100.825). Over 44 years there: absolute minimum 9.9 °C, 1st-percentile night 15.3 °C, 99th-percentile day 42.0 °C.
