cross_totals#
- metpy.calc.cross_totals(pressure, temperature, dewpoint)#
Calculate Cross Totals from the pressure temperature and dewpoint.
Cross Totals formula derived from [Miller1972]: CT = Td850 - T500
where:
Td850 is the dewpoint at 850 hPa T500 is the temperature at 500 hPa
Calculation of the Cross Totals is defined as the difference between dewpoint at 850 hPa and temperature at 500 hPa. This is a part of the Total Totals Index.
