transi{\c{c}}{\~o}es da esta{\c{c}}{\~a}o quente para a fria
(E\$_q-f\$) e da esta{\c{c}}{\~a}o fria para a
quente(E\$_f-q\$) foram identificadas atrav{\'e}s dos dados de
temperatura do ar de 14 esta{\c{c}}{\~o}es meteorol{\'o}gicas
do INMET, no per{\'{\i}}odo de 20 anos (1989 a 2008). As
E\$_q\$, E\$_q-f\$, E\$_f\$ e E\$_f-q\$ tiveram suas datas
de in{\'{\i}}cio determinadas por meio do crit{\'e}rio da
temperatura, baseada nas temperaturas m{\'e}dias di{\'a}rias das
E\$_q\$ e E\$_f \$ e,depois, seus in{\'{\i}}cios foram
ajustados mediante a passagem de sistemas frontais. O
in{\'{\i}}cio m{\'e}dio da E\$_q-f \$ ocorreu na p{\^e}ntada
17 e o da E\$_f \$ na p{\^e}ntada 27,nos quais ocorreram
passagens de Sistema de Frontal (SF) no litoral do Estado. O
in{\'{\i}}cio das E\$_f-q\$ e E\$_q\$ aconteceu, em
m{\'e}dia, nas p{\^e}ntadas 47 e 71, respectivamente, e estas
foram marcadas por per{\'{\i}}odos com aus{\^e}ncia de passagem
de SF, em m{\'e}dia de 15 dias na E\$_f-q\$ e de 13 dias na
E\$_q\$. Ap{\'o}s a determina{\c{c}}{\~a}o das datas do
in{\'{\i}}cio e fim das E\$_q\$ e E\$_f\$ foram determinados
os eventos de invernicos e veranicos. Os casos de invernicos foram
mais frequentes no m{\^e}s de mar{\c{c}}o e os de veranicos no
m{\^e}s de julho. Neste trabalho tamb{\'e}m foi realizada, em
uma segunda etapa, uma investiga{\c{c}}{\~a}o para determinar as
datas de in{\'{\i}}cio da E\$_c\$ e da esta{\c{c}}{\~a}o
seca (E\$_s\$) no Estado de S{\~a}o Paulo, atrav{\'e}s do
crit{\'e}rio da precipita{\c{c}}{\~a}o, utilizando dados de
precipita{\c{c}}{\~a}o pluvial do INMET e DAEE. As E\$_c\$ e
E\$_s\$ foram determinadas para cada ano atrav{\'e}s do
crit{\'e}rio da precipita{\c{c}}{\~a}o pluvial. Nesse sentido,
a m{\'e}dia dessas datas para as esta{\c{c}}{\~o}es ocorreu nas
p{\^e}ntadas 66 (INMET) e 63 (DAEE), na E\$_c\$, e na
p{\^e}ntada 19, na E\$_s\$ em ambas as fontes de dados. O
in{\'{\i}}cio das E\$_c\$ tamb{\'e}m foi determinado para
cada ano pela m{\'e}dia das p{\^e}ntadas climatol{\'o}gicas,
sendo constatada uma diferen{\c{c}}a de 4 p{\^e}ntadas entre
elas devido {\`a} suaviza{\c{c}}{\~a}o na m{\'e}dia dos dados
de precipita{\c{c}}{\~a}o climatol{\'o}gicos. ABSTRACT: In this
study the onset and the end of the warm (E\$_q\$) and cold
(E\$_f\$) seasons and the delimitation of the rainy season in
S{\~a}o Paulo State were determined. The dates of the beginning
of E\$_q\$ and E\$_f\$ and the transitions from the warm to
the cold season (E\$_q-f\$) and the transitions from the cold to
the warm season (E\$_f-q\$) were determined using air
temperature data from 14 meteorological stations of INMET for a
period of 20 years (1989-2008). The dates of the beginning of
E\$_q\$, E\$_f\$, E\$_q-f\$, E\$_f\$ and E\$_f-q\$ were
obtained using a temperature criterion and observations of cold
front passage. The results showed that the beginning of
E\$_q-f\$ and E\$_f\$ occurred in the pentads17 and 27,
respectively, where there were cold front passages in the litoral
of S{\~a}o Paulo State. The beginning of E\$_f-q\$ and
E\$_q\$ occurred, in the average, in the pentads 47 and 71,
respectively. In these periods there was absence of cold front
passage (in the average 15 days and 13 days for E\$_f-q\$ and
E\$_q\$, respectively). After the delimitation of the dates of
the onset and the end of E\$_q\$ and E\$_f\$ the events of
little winter and summer were determined. The little winter cases
occurred more frequently during March while the little summer
events were more frequent during July. In a second step, in this
study an investigation of the dates of the beginning of the rainy
(E\$_c\$) and dry (E\$_s\$) seasons in S{\~a}o Paulo State
based on a precipitation criterion was made. For this purpose,
rainfall data from INMET and DAEE were used. E\$_c\$ and
E\$_s\$ were determined for each year using a precipitation
criterion. In the average E\$_c\$ occurred in the pentads 66
(INMET) and 63 (DAEE) while E\$_s\$ occurred in the pentad 19 in
both the data sources. The beginning of E\$_c\$ was also
determined for each year and by the average of the climatological
pentads. A difference of 4 pentads between the two cases was
obtained due to the smoothing of the climatological precipitation
data.",
