short term now weather forecast
Circulation background field analysis
weather pattern analysis
Scale analysis in weather maps
water vapor conditions
850hPa wet zone
T-Td<=5℃
500hPa dry area
>15℃
stratification conditions
500hPa cold tank
850hPa warm ridge
Temperature difference
850-500
>25℃ is unstable
Lift trigger conditions
Shear lines and groove lines of each layer
ground convergence line
Precipitation areas are prone to occur near the ground convergence line
Determine weather type
High altitude trough
(Vortex/trough) rear northwest airflow type
Sub-high edge type
Tropical System
vertical wind shear
high and low altitude jet stream
The right side of the high-altitude exit and the left side of the low-altitude exit are generally precipitation areas.

Along with the warmth and against the cold
Feature height
0°C layer
The lower the altitude, the easier it is for hail to occur, generally <5km
-20℃ layer
The lower it is, the easier it is to produce hail, generally <8km
Diagnostic analysis of physical quantities
stratification conditions
CAPE index
When the time difference is large, it is necessary to adjust the non-insulatable line
The larger the value, the more unstable it is, generally >1000 or so.
K index
The larger the value, the more unstable it is, generally >35
Sabouraud Index (SI)
When <0, it is judged as unstable.

summary
short term weather forecast
Identification and analysis of mesoscale systems
Analysis of satellite cloud images
Convection clouds and their morphological changes, strong convective weather is prone to occur in areas with large brightness temperature gradients
Analysis of radar images
basic reflectivity
Combined reflectance
Strong echo center>35dBZ
train effect
bow echo
V-shaped echo
three-body scattering
Determine if hail is likely
Sectional view
Determine the center of mass height, whether it is greater than 5Km, and determine hail
Heavy precipitation generally echoes to ground
Hail has high-hanging strong echoes, hanging echoes, and bounded weak echoes.
Radial velocity
convergence and divergence
