Bob Blog 21 Nov

Bob McDavitt's ideas for sailing around the South Pacific.
Disclaimer: Weather is a mix of pattern and chaos; these ideas are from the
patterned world.
Compiled Sunday 21 November 2021

In the illustrated edition at
metbob.wordpress.com/2021/11/21/bob-blog-21-nov/ there are to screen shots
of EUMETSAT satellite imagery showing long lines of patterned cumulus,
chaotic cumulonimbus, and speckled squalls.

TROPICS
We are continuing with the typical mid-November hiatus with no cyclones
around at present.

WEATHER ZONES
SPCZ=South Pacific Convergence zone.
The SPCZ is stretching from PNG across Solomon Islands and northern Vanuatu
to Samoa.
A convergence zone over French Polynesia by mid-week is expected to move
towards Niue late in the week.

HIGHS and LOWS
LOW L1 south of Rarotonga is travelling SE and deepening, stealing the wind
from the tropics and moving a convergence zone onto Tahiti by mid-week.
HIGH H1 east of NZ is moving east along 35to 40S faster than L1.
LOW L2 just south of Noumea tonight is expected to travel southeast to east
of NZ and then go east following the L1/H1 combo.
LOW L3 is just west of South Island tonight and expected to cross NZ on
Monday and then move off to the east southeast.
HIGH H2 is expected to move from Tasmania to central NZ by mid-week and then
go northeast, allowing LOW L4 to spread from inland Australia to Tasman
Sea/southern NZ by end of the week.
After L2 it looks Ok to sail westwards to Australia or southwards from Fiji
to Opua until around Wed 1 Dec.
