How 2023 spread of world temperature compare with pat 80 years.

The graph at www.bbc.com/news/science-environment-67861954
shows a histogram for each year since 1940 and reveals the trend of Climate change .
A new edition of NOAA's Climate spiral graphic is at svs.gsfc.nasa.gov/5190/
Recent measurements in the ocean are outstanding...
The annual MONSOON reaches Darwin a few days ago, around a week or two LATE.
Rain starts, pressure drops and a gusty NW wind arrives.

TROPICS
TC BELAL near Madagascar follows ALVARO, which bothered southern Madagascar last week.
The MJO, a burst of extra energy in the tropics, is moving from Indian Ocean towards NW Australia over next few weeks, increasing the potential for cyclone formation around the "top end" of Australia.

WEATHER ZONES
The South Pacific Convergence zone is strengthening between north Australia and Vanuatu across the Coral Sea and lapping onto Fiji at times.
A tropical low L2 may develop near Fiji by mid-week and go south.
Another tropical Low L3 may deepen over Coral Se by end of the week. Keep a WATCH on this.

HIGHS and LOWS
HIGH H1 is lingering east of NZ.
There is a trough crossing NZ tonight and Monday.
This trough is expected to be followed by High H2 from Tasmania.
And following that L1 should cross Tasmania on Wednesday and Thursday with peak southerly swell early Friday.
