From the monsoon wiki page

describe[s] seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern

If we encode it as Subclass of season perhaps we go with the following definition (mirroring what we did for warm season and cold season

A season during which the average rainfall of a planetary part exceeds that of all other seasons it endures during a season generating process.

Comment:

Monsoon seasons typically occur in west Africa, Asia and Australia.

perhaps this could be the monsoon season class and we could have another class for the raining process itself like monsoon rainfall

Subclass of water-based rainfall

def: dbxref1 dbxref2

A water-based rainfall process which occurs as a result of temperature and pressure imbalances above land and the sea resulting from monsoon winds bringing moist air inland. Such moist air cools at higher altitudes as it rises over the land, causing increased precipitation.

Axiom: 'causally downstream of' some monsoon winds

Hence we should also add the class monsoon winds

def: dbxref1 dbxref2

A periodic atmospheric wind which occurs when the temperature on land is significantly warmer or cooler than the temperature of the ocean. The resulting temperature differences cause pressure differences which result in the movement of winds from the ocean to the land.

Axiom: 'causally downstream of' some monsoon season

Good drafting, but don't forget the asymmetric heating bit.

I'd avoid this for now - there's nothing compositionally different about the rain, it just happened to fall during a monsoon season.

I'd definitely add monsoon wind, but condense the definition a bit

An atmospheric wind during which air masses flow from over an ocean towards a land mass, due to disequilibria between land and ocean surface temperatures.

it would be causally downstream or within, but watch out! This relation is for processes and seasons aren't process, but one-dimensional temporal regions (note the comment, but I think we can move seasons under 1DTR) delimited by processes.

@pbuttigieg The reason I had suggested a term from the causal relation between processes hierarchy is that it species the domain and range as occurrent (despite the name saying processes), hence I figured it ought to apply to a 1DTR or wherever in the occurent hierarchy we end up putting season

Proposed additions modified from above discussion:

monsoon season

Subclass of season

Def dbxref

A season during which changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea cause increased average rainfall of a planetary part relative to all other seasons.

Comment:

Monsoon seasons typically occur in west Africa, Asia and Australia. During monsoon seasons temperature and pressure imbalances above land and the sea result in the formation of monsoon winds which bringing moist air inland, which in turn causes increased rainfall as moist air cools at higher altitudes as it rises over the land.

Editors note:

Pending decision of placement of season as one-dimensional temporal region, we should add axioms cross linking to monsoon winds, as well as increased prevalence of water-based rainfall.

Good point. However, I don't think a 1DTR can really cause anything. Let's leave that out for now. I'll try a during which starts relation from the wind to the season. Is there such a thing as an out of season monsoon wind?
