How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to spring is recharge.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Phenology

the spring season dated by recurring life-cycle events such as leaf-out and flowering rather than by the calendar.

The spring season treated as a biological event: the window after winter when warming sets off leaf-out, flowering, and the return of animal activity. Phenology does not date spring by the calendar but by the recurring life-cycle events themselves, and Menzel et al. (2006) showed across Europe that spring onset, first leaf and first flower, has moved earlier as the climate has warmed. The referent is a time of year defined by how organisms respond, and its unit is a day of the year. It shares the word with the coil, the outlet, and the tide, but here spring names a season and its timing, and shifts in that timing are a signal of a changing climate rather than a property of any device.[1]

Unit
Day of year of the onset event, such as first leaf
Recovery means
Scored as the date a phenophase, first leaf or first flower, is first observed in a given year
Measured by
Observed phenophase dates from long-running networks, and growing-degree-day models that predict onset from accumulated warmth

Oceanography

the tide of greatest range, near new and full moon, when lunar and solar tidal forces line up.

The tide of greatest range, when high water stands highest and low water falls lowest, occurring near new and full moon as the lunar and solar tidal forces line up. Here spring carries its old meaning of a rising or a bursting forth, not the season and not elasticity; the opposite, minimal-range tide is the neap. Doodson's (1921) harmonic development of the tide-generating potential expresses the fortnightly spring-and-neap cycle as a beat between lunar and solar constituents, so a spring tide is a predictable phase of that expansion. The referent is a recurring tidal condition, and its unit is the tidal range at those tides. It collides with the season by pure accident of the word, since the two share no mechanism.[2]

Unit
Tidal range at springs, in metres
Recovery means
Identified as the maximal-range tides near syzygy, or as the peak of the fortnightly beat in the harmonic expansion
Measured by
Tidal range from a tide gauge, and the amplitude of the fortnightly constituent recovered by harmonic analysis
